Mineral resources provide inputs and raw materials for agriculture, power generation,
construction activities and other industries. These are vital resources for development of
any country. As the mineral resources are limited and non-renewable, it becomes
imperative to achieve the best use of available mineral resources by scientific methods
of mining along with highest safety standards. There has been quantum jump in the
output of coal, metal, non-metallic and oil sector mines in our country.
Mining activity being hazardous in nature, persons working in this industry are exposed
to risk of health and safety. Every accident whether fatal, serious or leading to
permanent disability causes suffering to the victims and their family members.
The Annual Report pertains to occupational safety and health matters of persons
employed in mines in the country. The accident figures for the year 2007 has shown a
decreasing trend in both coal and non-coal sectors. In the coal sector, there were 77
fatal accidents resulting in 79 fatalities. In non-coal sector, there were 53 fatal accidents
resulting in 61 fatalities.
A review of the accident statistics for the Indian Mines over the last century indicates that
the fatality rate per thousand persons employed has shown a consistently declining
trend from 0.91 in 1951 to 0.20 in 2007 in coal mines, and 0.67 to 0.38 in non-coal
sector. A detailed analysis of accidents has been made in the report which reveals that
the fatality rate has declined during the last two decades both in coal and non-coal
mines.
The main cause of accidents in underground coal mines has been due to ground
movement while in opencast mines it is transport machinery. Accident due to ground
movement has contributed about 22% and due to transport machinery it has been 38%
during the year 2007. Looking at the last five years trend ground movement has
contributed about 28% and transport machinery 36%. Thus special attention needs to be
paid for reducing the number of persons getting exposed to green roof areas which is
preventable by adopting mechanized loading system and matching support system.
In this volume, roof fall accidents have been critically analyzed for the last five years and
have been illustrated by graphs. In case of opencast mines, due attention is required to
be paid for proper design of mine layout, proper maintenance of machineries, especially
those deployed through outsourcing. A strict implementation of code of traffic rules is
also required. The importance of imparting proper training to workers and supervisors
employed in mines need special attention. Workers’ participation in safety management
and role of Workmen’s Inspector have to be given due importance.
Mining activity extends to all over India having unique blend of big and small, manual
and mechanized; surface, opencast and belowground mines in coal, non-coal, oil and
Natural gas. Inspite of limited number of officers, staff and various constraints, we are
putting our best efforts in promoting safety in mines.

DGMS Annual Report,2007
1.0 Introduction
Under the Constitution of India “Regulation of Labour and Safety in Mines and Oilfields” is a
central subject (Entry 55 of the Seventh Schedule of Article 246). The matter is regulated by
the Mines Act, 1952 and the Rules and Regulations framed thereunder. It extends to whole of
India including territorial water i.e. upto 12 nautical miles in the sea measured from
appropriate base line. These statutes are administered by Directorate-General of Mines Safety
(DGMS) under the Union Ministry of Labour & Employment.
1.1 Historical Background
Although exploitation of minerals has been going on in the country from pre-Christian era, it was
only towards the end of 19th Century that attempts were made by the state for regulation of
employment and working conditions therein. Following the International Labour Conference in
Berlin in 1890, the then Government of UK through the Secretary of State for India asked the
Government of India to consider the desirability of undertaking legislation for inspection of
mines in general and coal mines in particular and for regulation of employment therein of men,
women and children. Accordingly in 1894, Mr. James Grundy was appointed as first ever
Inspector of Mines in India within the organization of Geological Survey of India. Mr. Grundy
recommended that provisions be made for the minimum age of employment; notice of opening
and of accidents, first-aid, management and supervision etc. Major disasters at Kolar Gold Field
in 1897 and at Khost Coal Mines, Baluchistan (presently in Pakistan) in 1898 expedited
finalisation of the first Mines Act which was enacted on 22nd March, 1901. A Bureau of Mines
Inspection was started in Calcutta on 7th January 1902 to administer the provisions of the
Mines Act, 1901. The organization was renamed as Department of Mines and its office was
shifted to Dhanbad in 1908. In 1960, the organization was renamed as Office of the Chief
Inspector of Mines. Again in 1967 the name of the organization was changed to Directorate-
General of Mines Safety (DGMS). In 1988 DGMS was declared a Scientific and Technological
Organization.
Apart from administering the Mines Act and legislation framed thereunder, DGMS also
administers certain allied legislation. A list of legislation administered by DGMS is given at
Appendix-I.
1.2 Organizational Set-up of DGMS
Directorate-General of Mines Safety is a multi-disciplinary organization with Inspecting Officers
from Mining, Mechanical and Electrical engineering and Occupational Health disciplines.
Officers appointed to different technical posts in DGMS are selected by U.P.S.C. They are
required to have Degree in Mining or Mechanical or Electrical Engineering with several years of
experience, varying from seven to ten years of working in responsible capacity in mines or allied
industry. Besides, officers of mining cadre posses First Class Mine Manager's Certificate of

Competency. The Occupational Health cadre is manned by qualified and
medical personnel.
experienced
The organization has its headquarters at Dhanbad (Jharkhand) and is headed by the Director-
General of Mines Safety. At the headquarters, the Director-General is assisted by specialist
staff-officers in mining, electrical and mechanical engineering, occupational health, law,
survey, statistics, administration and accounts disciplines. The headquarters has a technical
library and S&T laboratory as a back-up support to the organization. Extensive computerization
has been done in head office and in the field offices to upgrade the standard of work. The head
office and some of the field offices have access to the internet enabling these to place
themselves at par with other developed countries of the world so far as the communication with
the use of computer is concerned. DGMS has a plan to establish a network for all its offices
through Internet. A web page on DGMS has already been launched during the centenary year.
The field organization has a two-tier network of field offices. The area of jurisdiction of DGMS
covering the entire country is divided into six zones, each under the charge of a Deputy
Director-General. There are three to four Regional offices under each zonal office. Each
Region is under the charge of a Director of Mines Safety. There are in all 21 such Regional
Offices. Sub-regional offices have been set up in important areas of concentrated mining
activities away from Regional office. There are five such sub-regional offices, each under the
charge of a Deputy Director. Each Zone, besides having inspecting officers of mining cadre has
officers in electrical, mechanical engineering and occupational health disciplines.
Organization chart of DGMS are at Appendix-IIA & IIB. Table - 1 shows the discipline-wise
strength of inspecting officers as on 31.12.2007. A statement showing posting of Group ‘A’ &

2.2.3 Analysis of accidents
All fatal accidents and major serious accidents were inquired into by officers of DGMS. An
analysis of accidents enumerated in the following paragraphs is based on the findings of such
enquiry and information submitted by the mine management.
2.2.3A By place
Total 77 fatal accidents involving 79 persons occurred during the year 2007 compared to 78
fatal accidents and 137 fatalities during 2006. Fatality rate (overall) has decreased to 0.20 in
2007 from 0.36 during the year 2006. Serious injury rate during the year 2007 has increased
to 2.38 as compared to 2.31 in 2006 for overall injury rates. 25(32%) fatal accidents occurred
belowground with a fatality rate of 0.12, 36(47%) in opencast workings with fatality rate of 0.55
and 16(21%) in surface operation with fatality rate of 0.13 during the year 2007. It may be
mentioned that out of 372,000 average daily employment 49% was in belowground workings,
21% was in opencast workings and the remaining 30% was engaged in surface operations.

2.2.3B.2 Roof fall
Strata control is a major problem affecting safety and productivity in underground mines.
Experience of the past clearly brings out that roof fall is one of the predominant causes of
fatalities in belowground coalmines and that trend continues even today. There were 17
accidents due to ground movement involving 17 fatalities and 5 serious injuries occurred due
to this cause during the year 2007, out of which 13 accidents were due to fall of roof and 4
accidents were due to side fall(belowground). Roof fall accidents accounted for 16.88% of all
fatal accidents in coal mines and it contributed 52% of all fatal accidents in belowground
operations. Further critical analysis of roof fall accidents for the last five years 2003 to 2007
revealed the following:
I. Physical and Working Condition factors -
1. Method of work: Accident mainly occurred in board and pillar development and
depillaring. 49% of the fatal accidents occurred in B&P development followed by
depillaring districts (33% in caving districts and 9% in stowing districts). In 2% cases
accident occurred in longwall faces (stowing) and 7% in other places.
2. Height of working: 84% of the fatal accidents occurred in gallery height upto 3m and
15% in 3m. to 5 m.
3. Width of gallery: 40% of the fatal accidents occurred in width of galleries between
4.01 -4.50m, 31% above 4.50m, 18% between 3.51-4.00m, 8% between 0 -3.0m and
3% between 3.01 -3.5m.
4. Distance from face: 52% of the accidents occurred within 5 m. of the working face,
10 % between 5.01 to 10m, 7% between 10.01-20m and 10% above 20m from the
working face. Thus 62% of the accident occurred within 10 m. of the freshly exposed
17

DGMS Annual Report,2007
roof from the face of working. About 21% of the accident occurred in other roadways
where either roof supports were being replaced or no attention was paid for checking
old existing supports.
5. Type of support: 35% of the fatal accidents accounted in areas supported by timber
support only, 31% in roof bolts & others and in 1% of the cases supports were not
provided at all. Areas supported by timbers were more prone for roof fall. Steel
supports are more stable if they are fixed properly and in time.
6. Adequacy of support: Accident analysis revealed that in 49% of cases supports
provided was inadequate, which means sufficient number of supports were not
provided before engaging persons at work and majority of the accidents could have
been averted had proper supports were provided before engaging the persons at work
and front line supervisors been attentive for providing adequate supports.
7. Operation at the time of accident: 27% of the fatal accidents occurred during
loading operation (manual), 9% during supporting, 8% during dressing, 5% during
drilling thus 49% of the accidents occurred during primary job of face preparation and
manual loading. This can be avoided by providing adequate training to the face
workers for paying more attention towards identification of bad roof and testing for its
weakness and by providing temporary supports before erecting permanent support.
15% of the cases occurred during withdrawal of supports and 22% in other activities.
8. Time elapsed after blasting: 33% of the roof fall accidents occurred within 30
minutes of blasting operation which correlates with the operation at the time of
accident as mentioned above. This also means that sufficient time is not allowed for
the roof to settle before engaging persons. 19% of the fatal accidents occurred
beyond 2 hours of blasting operation, 12% between 1 to 2 hours and 2% occurred
between ½ - 1 hour. In 34% of cases no blasting operation was carried out within 4
hours.
II. Geological factors -
9. Thickness of seam: 45% of the roof fall accidents occurred in coal seam having
thickness upto 3.0 m., 36% in 3 to 6 m, 9% in seams with thickness above 9m and
7% in seams with thickness between 6-9m. Thus roof fall occurred in all types of coal
seams irrespective of their thickness.
10. Depth of cover: 41% of the roof fall accidents accounted in depth of cover upto 100
m, 33% between 101 to 200m and 17% of roof fall accidents occurred between 201 to
300m.
11. Thickness of fall: 30% of the roof fall accidents occurred in thickness of fallen strata
varying between 0.16 to 0.30m, 28% between 0 to 0.15m, 24% between 0.31 to 1.0m
thick and 17% beyond 1.0m thick. Thus 58% of the fatal accidents occurred in
thickness of fall between 0 to 0.30m. Fall of the roof was mainly due to geological
18

DGMS Annual Report,2007
reasons such as presence of slicken sides, hidden slip planes, or due to weathering of
strata etc. which could have been effectively controlled had adequate and timely
supports been provided.
12. Nature of fallen strata: 40% of the roof fall accidents occurred due to fall of sand
stone roof, 23% each due to coal and shale, remaining cases were due to
combination of any two indicating that practically all types of roof is likely to fall in
absence of adequate supports.
III. Personal factors -
13. Designation: 45% of the persons involved in roof fall accidents were loaders, 26%
were support men, 7% were supporting and supervisory staff and 3 % each were
drillers and dressers. Mainly face workers were involved in the accidents as they are
first to approach the face and stay beneath the green roof areas for longer duration.
14. Age: 27% of the persons involved in the roof fall accidents were in age group 46-50
years, 22% in the age group 41-45 years, 14% between 51-55 years, 12% each in the
age group of 31-35 years and 56-60 years and 10% in the 36.40 years . The available
data indicates that more susceptible were between 46-50 years which accounted for
27% of the total fatalities.
15. Shift of working: 59% of the roof fall accidents took place in 1 st shift, 21% in 2 nd shift
and 20% 3 rd shift. Thus roof fall occurred almost equally in 2 nd and 3 rd shift but more in
1 st shift as more number of persons worked during day time.
16. Hours at work: 29% of the roof fall accidents occurred in between fourth and fifth
hour, 23% between third and fourth hour and 20% each between first and third hour
and between fifth and seventh hour and 2% during last hour. No accident occurred
during first 1 hour.
IV. Management factors -
17. Responsibility: 36% of the roof fall accidents were caused due to fault of
management and Subordinate Supervisory Staff, 28% of the fatal accidents due to
fault of Subordinate Supervisory Staff alone and 7% were due to fault of management
alone. 12% cases were declared as misadventure.
18. Company: Company-wise analysis indicates that 79% of roof fall accident occurred in
CIL. Subsidiary-wise accidents data of CIL revealed that more accidents occurred in
SECL (20%) followed by BCCL (19%) and ECL (17%). For the companies other than
CIL, 19% of the roof fall accidents occurred in SCCL and 2% in TISCO.
Detailed statistical analysis of roof fall accidents that occurred during last 5 years have been
represented in tabular and graphically in the following tables:

A. Spontaneous Heating
In total 14(fourteen) cases of spontaneous heating were reported, 11 in belowground workings
and 03 in opencast workings.
Of the belowground heating, one (01) was in caved and sealed off panel, one (01) was in
sectionalized panel, three (03) were in depillaring panel under extraction and five (06) cases
were of spontaneous heating in fallen loose coal in old workings.
All the three (03) cases of spontaneous heating in opencast workings were due to entering of
air to belowground workings while developed underground were being extracted by opencast
method.
36

DGMS Annual Report,2007
Contributory factors for spontaneous heating:
The primary contributory factors which lead to spontaneous heating and thereby fires:
• Non-sectionlization / improper sectionlization of old workings.
• Not cleaning the old galleries and return airways off fallen coal and not treating
thoroughly with stone dust.
• Sluggish ventilation in old workings and depillaring areas.
• Working the depillaring panel beyond the incubation period.
• Not filling up the surface cracks formed due to subsidence and causing leakage of air
into the sealed off areas and old workings.
• Not making and maintaining the isolation stoppings as prescribed.
• Non provision of latest carbon monoxide gas detecting devices.
Corrective measures:
• Rate of extraction has to be made faster by deploying well maintained loading
machines and loss of coal in the goaf has to be minimized.
• Isolation and sectionlization stoppings have to be regularly inspected as per
statute to detect early stage of spontaneous heating.
• Fallen loose coal has to be cleaned off regularly.
• Surface area above the goved out panels shall be filled up to avoid breathing of
air.
• All the galleries exposed on the side of entries to the belowground workings in the
seam shall be covered effectively to avoid breathing of air through those galleries.
• Rib of coal left as barrier between opencast working and belowground working
need to be covered to prevent formation of return circuit through the
cracks/fissures developed at the surface.
B. Other Fires
In total five (05) cases of outbreak off fire other than due to spontaneous heating have been
reported, four (04) from belowground working and one (01) from opencast working.
Of the belowground fire, three (03) are the case of migration from adjacent working / panel or
jumping out from the isolation stopping and one (01) was accidental fire occurred due to
negligence of welder while using flame welding to cut old belt section girders.
There was one case of fire which broke out in an opencast Drill m/c (HEMM) due to electrical
short circuiting.
37

DGMS Annual Report,2007
Corrective measures:
• Timely action has to be initiated if active fire is known be existed behind the stoppings.
• Reinforcement of stoppings and cleaning of return airway to prevent choking shall be
done.
• Adequate precautions shall be taken as per statute while using flame or electric
welding or repairing apparatus belowground.
• Proper code of practice for prevention of fires in HEMM should be framed and
implemented.
C. Premature collapse of workings or failure of pillars/benches
There was one case of premature collapse of workings due to non-coincidence of workings in
multi section contiguous workings and theft of coal by villagers in the top seam.
D. Influx of Noxious Gases
There was one case influx of noxious gases in which an excavation in a quarry got punctured
with a developed gallery of belowground workings and smoke & fumes with substantial
quantity of ‘Co’ started coming out.
• Substantial thickness of barrier shall be left between opencast workings and
belowground workings.
E. Ignition or occurrence of inflammable gas
There was no case of ignition or occurrence of inflammable gas.
F. Irruption of water / Landslide
There are two cases of irruption of water /land slide reported.
In one case breakdown of pump lead to increase of water and found way to another working
through an inter connection and in another case due to heavy and unseasonal rains the
catchments area got overflowed onto the haul road leading to wash out of haul road material
into the coal face being worked 25 mt. below, to entrap 11 Tippers and 04 pay loaders idling
thereat.

2.6 Vocational Training
Recognizing the need for safety education to enable the mineworkers to
prepare them to
face the challenges of mining, the Mines Vocational Training Rules were framed in 1966.
These rules provide the provision for construction of mine vocational training centers, initial,
refresher and special training to mine workers, appointment of training officers, instructors,
proper training aids and equipments. It also provides for payment to trainees during the
training period. Progress of vocational training in coalmines during the year 2007was reported
to be as follows.

2.7 Workmen’s Inspector, Safety Committee & Welfare Officers
Much greater strides in safety can be achieved by participation of workmen in safety
programme, the twin institutions of 'Safety Committee & ‘Workmen’s Inspector’ have been
conceived and given the statutory backing. DGMS is also associated with training of
Workmen’s Inspectors to make them effective in discharge of their duties. In coal mines
almost all the eligible mines had Workmen’s Inspector and Safety Committee. The table below
shows the status of appointment of Welfare Officer, Workmen’s Inspector and formation of
Safety Committees during the year 2007.

3.2.2 Analysis of Accidents
The analysis of accidents presented below is based on the findings of enquiries into fatal
accidents conducted by officers of DGMS and information regarding serious accidents
received from the mine management.
3.2.2.1 Ground Movement
Number of accidents and fatalities due to ground movement shows a wavy trend in the last
five years indicating that it is the high time for the mine management to think and execute an
effective plan to reduce fatal accidents due this cause. Percentage wise there were 10 (19%
of the total) fatal accidents due to ground movement in the year 2007 as compared to 10 (17%
of the total) fatal accidents due to ground movement in the year 2006.
3.2.2.1A Roof fall Accidents
There was 1 (1.89% of total accident) fatal accident due to roof fall during the year 2007 in
non-coal mines involving 1 person when compared to nil accident during previous year.
3.2.2.1B Side fall Accidents
There were 7 (13% of total accident) fatal accidents due to side fall during the year 2007
involving 17 persons when compared to 6 involving 13 persons during previous year.
3.2.2.2 Transportation machinery (Winding)
There was no accident reported due to transportation machinery (winding) during the year,
2007.
57

DGMS Annual Report,2007
3.2.2.3 Transportation machinery (other than winding)
There were altogether 22 (29.73% of all fatal accidents) accidents involving 22 fatalities due to
transportation machinery (other than winding) during the year 2007.
The cause-wise details may be seen from the following table:-

• Loaded tipper traveling down suddenly the right side main leaf spring failed and giving
uncontrolled movement towards the right, hit and ran over a female worker. Loaded
tipper rolled back and hit a female worker.
• Tipper hit and run over a tipper operator.
• Tipper Khalasi injured during reversal for unloading, Khalasi fell and topped up side
down to ground caused injury and death.
• Tipper helper seriously injured due to Oil in the hose suddenly drained when the joint
was opened and the dump body fell crushing the helper to death.
• Empty tipper rolled back and fell into the ditch causing bodily injury and death. Empty
tipper had uncontrolled run over a bridge and driver lost control of vehicle and jumped.
Driver and helper injured. Helper died after some time.

It is seen that most accident due to transportation machinery and other machinery were
caused due to operator’s negligence, indiscipline and lack of supervisions. Improved
standards of training and education of workers are necessary to control such accidents. In
some cases the equipment failure was observed due to poor maintenance. It was also
observed that non provision of safety feature as per DGMS circular in equipment is also
causing accidents.

DGMS Annual Report,2007
6.0 National Safety Awards (Mines)
6.1 Introduction
During the post-independence era, the mineral industry in India has achieved tremendous
growth and also imbibed the latest mining technologies. Along with this growth, there has been
corresponding awareness of the need to protect the health and lives of workers. The
Constitution of India casts an obligation on all of us to ensure just and humane conditions of
work. To give due recognition to outstanding safety performance at the national level, the
Ministry of Labour, Government of India, instituted the National Safety Awards (Mines) in 1983
for the contest year 1982.
6.2 Scope
The scheme is applicable to all mines, which come under the purview of the Mines Act, 1952.
Such mines have been classified into 7 groups as given below:
i. Coal mines - Below ground with difficult mining conditions
ii. Coal mines - Belowground (others)
iii. Coal mines - Opencast
iv. Metal mines - Mechanized opencast
v. Metal mines - Manual opencast
vi. Metal mines - Belowground
vii. Oil mines
6.3 Schemes
Among different indices available, the following two have been accepted as indicator of safety
performance:
1. Longest accident free period (LAFP) in terms of manshifts worked during three
consecutive years ending with the contest year.
2. Lowest injury frequency rate (LIFR) during three consecutive years ending with the
contest year.
It is expected that every mine shall endeavour to improve its safety performance. A bad mine
has a high injury frequency rate. After obtaining a breakthrough, its next attempt should be to
achieve longest accident-free period in terms of manshifts worked.
6.4 Awards Committee
The awards committee is constituted by the Ministry of Labour & Employment with Director-
General of Mines Safety as its Chairman, eight representatives of mine managements, eight
representatives of trade unions and an officer of DGMS as its Member-Secretary.
78

DGMS Annual Report,2007
6.5 Mode of operation
An advertisement is released through DAVP in English, Hindi and other regional languages
inviting applications in prescribed proforma for National Safety Awards (Mines). An entry fee of
Rs.100/- per application is charged through a crossed IPO drawn in favour of the
Administrative Officer/DDO, DGMS and payable at Dhanbad Post Office. The prescribed
application form is jointly signed by the mine management and a workers’ representative.
6.6 Presentation of awards
National Safety Awards (Mines) for the year 2002 & 2003 was given away on 14 th February,
2007 at New Delhi by Hon’ble Vice President of India.
7.0 Conference on Safety in Mines
The Conference on Safety in Mines is a tripartite forum at the national level in which the
employers’ representatives, the trade unions’ representatives, the Government represented by
Ministry of Labour & Employment, DGMS, various administrative ministries/departments and
State Governments and associated institutions, professional bodies, service associations, etc.
take part. They review status of the safety in mining industry and the adequacy of existing
measures in a spirit of mutual cooperation. The conference also suggests measures for further
improvement in safety, welfare and health of mine workers. The first such Conference was held
in the year 1958 followed by the 2 nd in July, 1966, the 3 rd in 1973, the 4 th in 1978, the 5 th in 1980,
the 6 th in 1986, the 7 th in 1988, the 8 th in 1993, the 9 th in 2000 and the 10 th Conference was held

DGMS Annual Report,2007
8.0 Plan Schemes
DGMS is implementing four Plan Schemes to provide in-house technical support, namely:
(i) Study of Mine Accidents and Development of Mines Safety
Information System (SOMA)
The scheme has been formulated by merging two on-going plan schemes of DGMS, namely
“Development of Mine Safety Information System (DMSIS,1976)” and “Study of Mine
Accidents to Plan Preventive Measures (SOMA, 1976)”. In 2001-2002, i.e. the terminal year of
the 9 th plan, keeping the objective of integration in view, these schemes were merged into one
scheme “Study of Mine Accidents and Development of Mines Safety Information System
(SOMA)”.
(A) Accident Prone Mines:
A modified approach for identification of accident-prone mines was adopted; data from all the
mines of eleven coal companies were collected. In-depth analysis of all fatal and serious
accidents that occurred in all 517 coal mines and 9 lignite mines of the country during the
periods 2003-2007 were made and based on the outcome of the study, the accident-prone
mines were identified. This was done with a view to identify hazard potential of such mines and
draw up action programmes for formulation of mitigating measures through collective efforts of
Mine Management, Trade Unions and the Government.
The following table shows the number of accident-prone mines identified in different coal
companies in last five years.

LIGNITE 3 3 - 1 3
The respective companies were advised to take suitable steps from technical and
management point of view to identify the potential risk of the respective mines and to device
suitable corrective measures and implement the same in a time bound period so that the
accidents are reduced.
Reports of enquiry into all fatal accidents were scrutinized. Finalized causes and circumstances
leading to these accidents were compiled for inclusion in DGMS Annual Report.

Use of integrated steel support and steel props in coal mines
Roof bolting is extensively used as a system of support in Indian coal mines. However, in
certain areas of depillaring workings and other development workings, conventional supports
are also being used. In view of several fatal accidents due to fall of roof in roof bolted
workings including depillaring areas, a committee was constituted comprising mine
management, trade union, Central Mining Research Institute and Directorate-General of
Mines Safety to look into the issue at depth.
It has been suggested to strengthen the goaf edge support effectively and quickly. One such
option is to provide integrated steel support and steel props as and when the situation
demands. Before using the supports in coal mines they need to be tested to ascertain the
efficacy. A general minimum test standard for such supports has been detailed in Annexure-I
& II.
You are requested to give wide publicity amongst all concerned persons working in your area
about the same for information and compliance.

Protocol on use, care, maintenance, sampling & testing of Self-contained Self-
Rescuer (SCSR) under Regulation 191D (2) & (3) of the Coal Mines Regulations,
1957.
In view of the limitations of the Filter Self Rescuer as escape device and in pursuance to the
recommendation of the Ninth Conference on Safety in Mines as well as the New Kenda Court
of Enquiry, a meeting of users, regulators, scientific institutions, academicians and
manufacturers/suppliers was held on 16 th March, 2004 to consider introduction of SCSR in
Indian mines. As decided in the meeting a “committee” representing users, regulators,
scientific institutions and academicians was constituted to recommend mode of introduction of
SCSR.
The committee recommended “use of Self contained or Oxygen type Self Rescuer (SCSR) in
all degree III and degree II gassy mines and in all fiery mines to be enforced with immediate
effect”. Based on the recommendations of the said committee a Statutory Order under
Regulation n191D of the Coal Mines Regulations, 1957 was issued on 5 th January, 2007.
To ensure proper quality of supply, efficient use, care and maintenance of SCSR a
comprehensive protocol on its use, care, maintenance sampling and testing, as suggested by
the working group constituted for the purpose and the manufacturer/suppliers, has been
formulated as mentioned below. It is expected that the “protocol” would be religiously
implemented by all concerned:
A. USE, CARE & MAINTENANCE:
1. The Owner, Agent and Manager of a mine with below ground workings, upto the
travel time of one hour, shall ensure that the rated duration of the Self Contained Self
Rescuer (SCSR), provided to any person, is not less than one hour. However, in
respect of workings with more than one hour travel time adequate number of SCSR
(not less than the maximum attendance of the largest shift) shall be placed at suitably
designed “Safe Haven” or “Refuse Chambers” located at convenient point(s).
2. Contrary to the above, use of SCSR of rated duration less than 60 minutes and upto
30 minutes for a specific district or panel of the mine may be permitted, on request of
the Owner/Agent/Manager of the mine in writing, by the concerned Regional
Inspector of Mines.
3. Every person required to go down the mine shall be provided with a belt/harness of
suitable design to enable him to carry the SCSR as well as other gadgets
conveniently on his body.
4. Special racks of suitable design shall be provided for storage. The storage area
should be away from heat source. Units shall be cleaned regularly with wet cloth in no
case organic solvents shall be used for cleaning of the SCSR.
5. Every unit in use shall be subjected to “daily visual check” for the seals (intact or not),
leakage indicator (change in colour), clamps (for any damage), belt loop (for any
damage) and container (for any damage or dent). Units found O.K. in visual check
only shall be issued and used. Damaged/defective unit shall be immediately
withdrawn from use and be kept separately.
6. Every SCSR on roll of the mine shall be subjected to “Leak Tightness Test”, as least
once in a quarter by a competent person duly authorized by the manager for the
purpose, in the following manner:
i. Place the apparatus inside the test box;
ii. Put the lever down to the slotted place;
iii. Close the lid of the box tightly;
iv. Release lever to its original place to create vacuum of about 20 mb as
displayed in the attached pressure/cacuum gauge &
A-23

DGMS Annual Report,2007
v. Watch the pressure/vacuum gauge for a minute, if the drop in the reading
is less than 5 mb the unit is considered to be leak tight and is fit to use or
else the unit shall be treated as failed and shall be withdrawn from the use.
7. Test result in respect of “daily visual check” and “Leak Tightness Test” with regard to
each & every unit shall be recorded in a bound-paged register kept for the purpose.
Every entry shall be signed by the person who has conducted the test and to be
counter signed by the Manager or any other official authorized by him in this regard.
8. The Manager shall prepare a code of practice for storage, use, care and maintenance
of the SCSR based on the model code provided by the Owner.
9. As far as practicable use of one type of SCSR shall be preferred in a mine.
B. SAMPLING & TESTING:
1.1 At the time of supply: Before a batch SCSR units are put to use samples at the rate of
three percent (3%) subject to a minimum of nine unit, for every batch of supply shall
be drawn at random for the testing by a joint sampling team comprising of
representatives from manufacturer/supplier and user at the user’s site.
1.2 Fifty percent (50%) of the above drawn sample (subject to a minimum of six units)
shall be sent to any of the approved/accredited laboratories for full bench test as per

Noise Levels and Noise Induced Hearing Loss among mine workers.
In continuation to DGMS Technical Circular No.18 of 1975 and NO.5 of 1990 on “Protection of
Workers against noise”, it is brought to the knowledge of all concerned that Noise is emerging
as an important and challenging health hazards for mine workers. With increasing
mechanization of mining operations and use of heavy machinery the noise level in mines
have increased over the years. Surveys conducted by this Directorate and other institutions
have shown that noise levels in majority of the mining operations are higher than the
recommended limit of 90 dB(A).
In an occupational health survey conducted in an belowground metal mine more than 80% of
workers showed evidence of Noise Induced Hearing Loss of 27.7% and 13.1% had severe
and profound hearing impairment. Noise Induced Hearing Loss was observed among all
category of mine workers but the prevalence was highest among workers engaged in drilling
operations. The occurrence and severity of NIHL was related to the degree of exposure to
noise and years of service in the mine.
In order to prevent occurrence of Noise Induced Hearing Loss among mine workers every
mining company should formulate long term strategies and comprehensive hearing
conservation programme which should have following components:
1. Noise Level Surveys including Noise Exposure Dose Profile of workers
2. Engineering and Administrative Controls
3. Awareness and Health Promotion Programmes on Noise and its effects
4. Personal Hearing Protection
5. Audiometric Examination of workers
6. Maintenance of comprehensive records of Noise Level Surveys
7. Periodic monitoring and review of Hearing Conservation Programme
All concerned are therefore advised to take necessary measures to prevent Noise Induced
Hearing Loss among mine workers and to conduct Noise Level Surveys including Noise Dose
Exposure Profile of workers.

Damage of belowground structures due to blast induced vibration in nearby
opencast mines.
As you are aware, stability of belowground coal mine openings, coal pillars, water dams and
ventilation & isolation stoppings in close proximity to operating opencast mines are likely to be
affected from blast induced vibration. In India, presently an increasing trend has been
observed to win top coal seams, whether it is virgin or developed and standing on pillars, by
opencast method wherever it is economical. The blast dimensions are also large with high
explosive density as well as quantum of explosives per blast, generating seismic disturbances
which may in turn affect the stability of roof and pillar, support system, ventilation/isolation
stoppings, water dams in belowground etc.
As the blast – induced vibration is likely to have an impact on the stability of the belowground
structures as mentioned above, it is imperative to assess the magnitude of the effect and
formulate a guideline for controlling damages to belowground structures due to surface
blasting.
A study in this regard was carried out by CMRI in a number of coal mines under varying geomining
conditions. A committee was constituted by the undersigned, comprising
representatives from mining industry, academic and research institutions and DGMS to
discuss the deliberate on the inferences of CMRI report and forward their suggestions
regarding framing guidelines on this issue.
With due consideration of the recommendations made by the committee, the methodology for
conducting trial blast, instrumentation strategy for measurement of blast induced vibration,
damage etc. and the threshold limits of vibration for different ranges of RMR are finalized, and
furnished as a guideline in Annexure-I.
It is suggested that the mine operators will take adequate measures to optimize and blast
design parameters in such a way that blast induced vibration in no way endanger the stability
and safety of the belowground workings and structures.
Guidelines for Stability of Belowground Coal Mine Workings due to opencast blasting.
1.0 Introduction
Annexure-I
The safety and stability of belowground coal mine openings, coal pillars, water dams,
ventilation and isolation stopping in close proximity to operating opencast mines are often
endangered from blast induced vibrations. The serious concern is possible damage to above
belowground structures from nearby large surface blasts. Any vibration produced rock fall or
minor cracks in isolation stoppings would be recognized as an unacceptable hazard.
2.0 Damage Criteria
Peak particle velocity has so far been considered as the best criterion for evaluating blast
vibrations in terms of its potential to cause damage. Extensive studies on the problem have
established that frequency of the wave has no significant impact on damage to belowground
A-28

DGMS Annual Report,2007
coal mine openings. The damage to the belowground openings in reference to opencast
blasting is generally classified into four categories.
1. No appreciable damage: No visible damage
2. Threshold damage: Formation of superficial cracks in pillars, roof,
isolation and/or ventilation stoppings, air crossings,
dams and other belowground structures.
3. Minor damage: Detachment of loosened chips from roof and/or
pillars, opening and lengthening of old cracks,
loosening of joints.
4. Major damage: Fall of rock/coal blocks from roof and/or pillars, cracks
in isolation/ventilation stoppings, serious weakening
of belowground structures.
3.0 Responses of roof and pillars
The roof of the belowground working vibrates with higher amplitudes of vibrations compared
to pillars. The attenuation of vibration in roof is fast that that in pillars. This indicates that the
pillars of belowground working experiences vibration for a longer period compared to the roof.
4.0 Measurement of blast induced vibrations
4.1 Instrumentation
The seismograph selected for monitoring blast-induced vibration shall be simple, light,
compact, easily portable, battery operated, digital output, triggering by geophone etc. Tri-axial
transducers for recording blast vibrations shall have a linear frequency range from 2 Hz to
250 Hz and capable of recording particle velocity upto 250 mm/s.
4.2 Methodology
The transducer of seismograph shall be placed in the junction of the roof with the help of
attachment provided by the manufacturer of the seismograph. It may also be placed in the
pillars at 1-2 m below the roof at a depth of 05-06 m inside the pillar. A minimum of a 20
observations corresponding to a minimum of 10 blasts shall be made for better prediction with
a high index of determination.
4.3 Predictor equation
The least mean square method of regression analysis shall be used for interpreting the data.
Since, the blasting has been performed on surface and the measurements are taken in
belowground, the square root scaling law shall be used for analysis and interpretation of data.
5.0 Guidelines on experimental blasting
5.1 Factors
Major factors affecting particle velocity of ground vibration are type and amount of explosives
charge used, distance from the blast site to the location of belowground workings, geological,
structural and physical properties of the rock that transmits the vibration and blast geometry.
Use of safe maximum explosives per delay, in-hole delays with Nonel systems, proper
burden, spacing and proper stemming of holes reduces blast induced ground vibrations.
5.2 Plan
A plan showing the opencast workings above the belowground coal mine n different
prominent shades shall be prepared. The plan shall incorporate all the belowground
structures including isolation/ventilation stoppings, different working faces, water dams etc.
Plan should also show the place of and location of vibration monitoring transducers in roof
and pillars.
A-29

DGMS Annual Report,2007
5.3 Study/Observations
In a particular mining area where opencast blasting is to be performed above the
belowground structures, experimental blasting shall be carried out, prior to commencement of
drilling and blasting operations by any research/Academic Institute for optimizing the blast
design parameters to restrict the vibrations in belowground workings within safe limit. The
type of instruments, the methodology and predictor norms as recommended in para 4.0 shall
be followed in measurement of blast induced vibrations. Based on the study, the safe charges
for the safety of belowground structures shall be determined and recommendations should be
made in the report.
5.4 Monitoring
In order to ensure effective control over the vibration and related damage there is a need of
regular in-house monitoring and the management should train the blasting personnel during
the experimental study and start observations on their own during the regular blasting
operations.
6.0 Recommended permissible standards of vibrations
6.1 Technical considerations
The degree of damage observed in the belowground openings is influenced by the RMR of
the roof rock. Thus, the damage criterion for belowground coal mine workings is based on
RMR, because it includes the parameters like layer thickness, structural features, rock
weather-ability and strength of the roof rock and groundwater seepage.
6.2 Permissible standards
The junctions of the belowground coal mine workings are more susceptible to blast produced
cracking than the galleries away from the junctions. The threshold values of vibration at the
junctions in terms of peak particle velocity has been given in Table-1 for different RMR of roof
rocks for the safety of belowground coal mine workings. The limiting values of vibration in the
pillar are also given below in Table-2.
Table-1: Threshold values of vibration for the safety of roof in the belowground workings for
different RMR.
RMR of roof rock Threshold values of vibration in peak particle velocity [mm/s]
20-30 50
30-40 50-70
40-50 70-100
50-60 100-120
60-80 120
Table-2: Threshold values of vibration for the safety of pillar in the belowground workings for
different RMR.
RMR of roof rock Threshold values of vibration in peak particle velocity [mm/s]
20-30 20
30-40 20-30
40-50 30-40
50-60 40-50
60-80 50
In view of complexities of the problems it is hoped that mine management would take
adequate measures as recommended above to ensure that the blasts performed near the
belowground workings are carried out with utmost care and precautions. The blast induced
ground vibrations should be within the permissible limits as specified above.

Blast-hole drilling for Opencast Coal Mines
It has been observed, during inspection of opencast coal mines, that some of the contractual
machinery used for blast-hole drilling operations, are truck mounted drills designed for tube
well drilling for sources of water. The following short comings have been observed with these
drills, when deployed in opencast coal mines for drilling in overburden and coal.
1. No inbuilt dust collection/suppression system is provided.
2. These water well drills, being truck mounted, require better infrastructure of road and
are less stable than Crawler mounted drills, which can march even in muddy roads
due to better gripping.
3. Drill operational control switches are located as the rear end of the truck and no cabin
is provided to operate it. Operators and helpers are required to be present in dusty
atmosphere.
Therefore, for safe drilling operations in opencast coal mines, if tyre mounted drills are
deployed, they should comply with the following:
All control switches for all drilling operations including tramming and setup, should be
centralized in a properly designed operator’s cabin, located at the drilling end. Drill should be
provided with hydraulically operated carousel/rod changer. Suitable hydraulic jacks, with
controls from operator’s cabin, should be provided for leveling of the machine. The drilling
machine should have efficient dust collection system.
Only proper type of blast-hole drill machine, designed for mining purpose should be used.
