(iii) every pillar or block of mineal left for the support of any structure on the surface; and
underground magazines, if any;
(iv) every important surface feature within the boundaries, such as railway, road, river, stream,
watercourse, tank, reservoir, opencast working and building which is within 200 metres of
any part of the workings measured on the horizontal plane;
(v) the general strike of the veins, lodes, reefs an mineral beds or deposits;
(vi) the position of every dyke, fault and other geological disturbance with the amount and direction
of its throw; and
(vii) an abstract of all statutory restrictions in respect of any specified workings with a referred to the
order imposing the same.
Whatever this plan is brought up-to-date the then position of the workings shall be shown by dotted line
drawn through the ends of the workings and such dotted line shall be marked with the date of the last
survey.
Provided that the Chief Inspector may, by an order in writing and subject to such conditions as he
may specify therein, approve any other method of showing the up-to-date position of the working of the
mine.
(c) A transverse section or sections of the workings through the shaft or shafts and main adits indicating
clearly the surface and the dips of the vein, lode, reef or mineral bed or deposit at different points; and
such sections of the strata sunk or driven through in the mine or proved by boring, as may be available.
(d) A vertical mine section or sections showing a vertical projection of the mine workings, where a reef,
vein, lode or mineral bed or deposit has an average dip of more than 30 degrees from the horizontal;
(e) A ventilation plan, and section where necessary, showing the system of ventilation in the mine, and in
particular –
(i) the general direction of air-current;
(ii) every point where the quantity of air is measured;
(iii) every air-crossing, ventilation door, stopping and every other principle device for the regulation
and dis tribution of air;
(iv) every fire-stopping and its serial number;
(v) every room used for storing inflammable material;
(vi) the position of fire-fighting equipment;
(vii) every water-dam with dimensions and other particulars of construction;
(viii) every pumping, telephone and ambulance station; and
(ix) every haulage and travelling roadway.
(f) A water-danger plan and section showing :
(i) the position of the working belowground; an every borehole ans shaft (with depth), drive, crosscut,
winze, rise, excavation and air passage connected therewith;
(ii) the position of every dyke, fault and other geological disturbance with the amount and
direction of its throw;
(iii) levels taken in workings belowground at easily identifiable points sufficient in number to
allow of the construction of sections along all drives, mainheadings and haulage
roadways;
(iv) every source of water such as river, stream, water-course, reservoir, water-logged
opencast workings on the surface, and also the outline of all water-logged workings
belowground lying within 60 metres of any part of the workings measured in any
direction ;
(v) every reservoir, dam or other structure, either above or belowground, constructed to
withstand a pressure of water or to control in inrush of water, along with reference to its
design and other details of construction;
(vi) surface contour lines drawn at vertical intervals not exceeding five metres (or ten metres
in the case of a mine where there are no working belowground ; or in cases of mines
