Coal mining

Choosing a mining method. The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining. Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in extracting a coal seam depends on many technological, economic, and social factors.

Glossary of Mining Terms

A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.

Tailings Filter Press | Dewatering Solutions for Mining ...

Dry Stack Tailings are becoming an increasingly viable and attractive alternative to tailing impoundments in the mining industry. A Filter Press delivers some of the best results from competing dewatering technologies. By dewatering tailings to a relatively "dry cake," this stable and stackable form of storage is ideal for mining companies.

Hot dry rock geothermal energy

Hot dry rock (HDR) is an abundant source of geothermal energy available for use. A vast store of thermal energy is contained within hot – but essentially dry and impervious crystalline basement rocks found almost everywhere deep beneath the Earth''s surface. A concept for the extraction of useful amounts of geothermal energy from HDR originated at the Los Alamos National Laboratory in 1970 ...
