Driving Headings, Coal Extraction and Mineral Processing
Driving Headings & Coal Extraction
Extraction involves all the steps of underground coal production. This begins with the driving of advance headings, includes extraction methods using ploughs and cutter drums and also the transport of the coal by chain conveyors from the coal face and belt conveyors along the roadways.
Based on our many years of experience in longwall mining we support mine operators in selecting the best possible method from a technical and economic point of view and contribute to optimising current operations.
Our focus is on underground measurements as well as on simulations and calculations for designing water sprays on heading and coal-cutting machines for reducing dust and preventing gas-dust ignition.
The Mineral Processing section deals with the engineering treatment of coal as well as other raw and waste materials. In the work special attention is paid to the mechanical steps in materials processing, such as crushing, grading, cleaning, separation and agglomeration as well as the separation of solids from liquids. Our focus is on investigations at laboratory scale and at pilot-operations scale as well as on simulations and calculations for designing, planning and optimising mineral processing and washing processes and the treatment of processwater.
On the basis of our services, operators of mineral processing plants can extract from the natural resources the greatest benefits by investing just a minimum of costs.
