Colloquium Objectives 

Ruhr University Bochum 

October 5 – 7, 2005 

The main objectives of the colloquium is to provide a forum for young scientists 

engaged in research in Computational Mechanics, to present and to discuss results 

of recent research efforts, to foster the exchange of ideas among various fields in 

Computational Mechanics and to support the progress of ongoing research. Ad- 

vanced computational methods and models for the numerical analysis of materials 

and of structures and the assessment of their suitability and robustness are in the 

main focus of the colloquium. The presentation of work in progress is welcome. 

The organizers hope, that the colloquium will also help to identify promising new 

research directions. According to the colloquium objectives, young scientists are 

invited to present results of their scientific work at the colloquium. Thematically 

arranged sessions and organized minisymposia, complemented by social events will 

provide ample opportunities for discussions in an informal atmosphere.

October 5 – 7, 2005 

The Ruhr District is one of the most diversified and culturally active regions in 

Germany. With about 5.3 million inhabitants, it is one of the oldest and most 

influential industrial regions in the world and it is nowadays a centre of business and 

services. Bochum is a modern cosmopolitian city with a population of about 400.000. 

It is located in the heart of the Ruhr District approximately 60 km from Düsseldorf 

and about 100 km from Cologne and changed over the last 40 years from a centre 

of coal and steel industries to a modern city with well over half of the population 

working in the service sector. Today it is also a city of greens: 33 parks, 170 further 

green areas and over 35,000 trees along the streets. Renowned museums (among 

them the famous Deutsches Bergbau Museum), theatres and lovely surroundings 

(from the river Ruhr and the Sauerland hills in the South to the Münsterland in the 

North) are a stimulating scene for living, studying and - for congresses. 

Ruhr University 

The University of Bochum is one of the most diversified of German universities. 20 

faculties offer about 100 subjects in the Natural and Engineering Sciences as well as 

the Humanities and Medicine. Almost 35.000 students study and 6.700 members of 

staff including 433 professors work at the university.

Welcome / Introduction 


October 5 – 7, 2005 

Dear visitors, we are pleased to welcome you in the demonstration mine of the Ger- 

man Mining Museum. It was built to give an insight into the world of underground 

mining and into minerst’ work. Today’s coal mines in the Ruhr area are a lot deeper 

than our demonstration pit. Most of the coal now comes from depths of about 

1000 m, whereas you have descended only 17 m. The difference in depth means a 

considerable difference in temperature, too. During their working hours Ruhr min- 

ers have summer temperatures throughout the year: in a real coal mine it is about 

20 - 30 ◦ C warm. 

Tunnelling machine 

This machine is made to cut the tunnels through the rock in order to get to the coal. 

In a working mine it would slowly move forward and cut through the rock using the 

red discs with chisels (front part of the machine). The stones are carried off by the 

conveyor you can see at both sides of the machine. The dust which is produced 

during the work goes off through the black tube hanging from the ceiling behind the 

machine. This is important to avoid the stone dust being breathed in by the miners, 

because it would cause an incurable lung disease. On the left side - painted green, 

hanging from the ceiling - you can see the laser device used to indicate the direction 

the machine is supposed to drill. The driver looks at the target fixed to the front 

and is thus guided by the laser beam. 

Drilling machine 

A big part of the tunnelling work in the mines is still done by the drilling and 

blasting-method, which is slower, but cheaper than the use of such huge machines 

as the one you have seen before. Using the drilling and blasting-method you first 

drill many deep holes into the rock face, fill them with explosive, close them again, 

and blast the rock. Afterwards you carry away the stones and then build your 

support in order to keep the tunnel open. The machine shown here, built in the 

nineteen-fifties and driven by compressed- air, might be used to drill the holes. The 

guide will switch it on and demonstrate the noise. 

163



Tobias the mining horse 

Tobias was the name of the last mining horse in the Ruhr area. In 1966, after a 

working life of 17 years, it left a coal mine in Recklinghausen. The horses had to 

pull trains of 8 to 10 wagons, charged with coal or stones. Today these trains are 

pulled by locomotives. 

Coal deposits in the Ruhr-area 

Between the grey rock on top and below you see a coal seam (stratum of coal) as 

one might find in this area. The coal seams are very different in size and position. 

Many of them are not even half as thick as shown here but on the other hand they 

may be twice or three times as thick.The average thickness in this region is small 

compared to other coal mining-areas on the earth. The differences in position - from 

horizontal to vertical - were caused by the strong movements of the parts of the 

earth crust. They forced the strata into today’s shape. On your right, in front of 

the coal there are two pneumatic hammers used in former days to extract coal. In 

the nineteen-twenties those hammers came into the Ruhr mines in large numbers and 

replaced the pickaxes. Another wave of mechanization started in the nineteen-fifties 

and extraction machines made the pneumatic hammers disappear by and by. 

Coal plough 

There are two types of machines used in German coal mines today. The one shown 

first on our tour is called coal plough (blue, with chains on both sides). It is pulled 

along the coal face, quicker than shown in our museum, and peels layers of coal 

from the bottom part of the seam. Conveyor and coal plough are pushed ahead by 

hydraulic power and thus work deeper and deeper into the coal. The top part of the 

seam loses its support and falls down. The coal which does not fall directly onto the 

conveyor is pushed aside by the plough. As miners work ahead, extracting the coal, 

they take their support with them in order to keep their place of work open and safe. 

In the nineteen-fifties, as shown here, this was still really hard work, which needed 

a lot of staff. The men had to disassemble the heavy steel construction, carry it 

ahead and reassemble it again and again. The cavity created by extracting the coal 

and moving the support is either filled with rock or you let it collapse. 

164

Coal cutter 


October 5 – 7, 2005 

The second type of machines used nowadays is called coal cutter or shearer loader 

(yellow). The wheel with the chisels would move inside the coal while the whole 

machine would move slowly along the coal face. Deep stripes of coal are thus cut 

from the bottom part of the seam. Today’s shearer loaders are designed in such a 

way that they cut the seam in full thickness, whereas with the older model here the 

top coal would have to fall down. The improved support we show here is moved 

by hydraulic power like a chain from which you pull ahead one link after the other. 

The few miners operating this hydraulic support lower two props connected by the 

blue bar on top, pull them ahead and move them up to carry the roof again. This 

procedure is repeated couple after couple, the whole line through. Together with 

the support the conveyor with the extraction machine on it is pushed ahead, too 

(this simplifies a bit). 

Rescuing-torpedo 

The torpedo shaped object on the floor may be used to rescue miners who are 

trapped in the mine after a collapse blocking the regular way to get back up. In 

such a case you will drill a hole into the cavity where surviving miners are trapped. 

The hole may be drilled from above - perhaps from the surface - or from a lower 

part of the mine. From above you would then lower a rescuing-torpedo through the 

hole hanging on a rope. From below the torpedo might be fixed to the drilling rod 

and pushed up. The rescuing-torpedo is used like a one-person-lift: one after the 

other miners are put in and then pulled out. 

Mining today 

In this coal face with its two gate roads we show you contemporary technical equip- 

ment. You are standing in the delivery road supported by steel arches and wire- 

grate. The ripper takes away the rock above the coal seam, which here is 2.7 m 

thick. The coal-getting machine in this face is a double drum shearer. The two 

drums measure 1.8 m in diameter and are adjustable in height on their arms. In a 

coal face of 300 to 400 m in length the drum shearer can move from one end to the 

other once or twice within one hour. With each cut it will take away 80 cm of coal. 

Dust development is suppressed by water nozzles on the drums. Along a roll curve

the chain conveyor carries the coal to the delivery road. Support shields keep the 

coal face open and protect the miners from falling rock and coal. After each cut of 

the drum shearer the shields push the conveyor together with shearer towards the 

coal and then pull themselves ahead, too. At the other end of the coal face there 

is the top road, which is here supported by roof bolts. Both junctions of the coal 

face and the gate roads are supported by individual props. In Germany hard coal 

is mined at depths up to about 1500 m today. In a face of 300 m length about 10 

miners would be at work. They operate the drum shearer, move the shields and 

keep the junctions of the coal face and roads safe.
