Equipment. NOTE: although the following sections deal with individual items of equipment in isolation it is noted a longwall face comprises a number of components that have to be fully integrated and work as a complete unit they cannot be designed and installed in isolation from each other and be expected to operate successfully.
In 2011 underground mining machinery accounted for % of Joy Global''s revenue (excluding LeTourneau) up from % in 2010. Underground mining machinery. Joy Mining Machinery (Joy) was the worlds largest producer of high productivity underground mining machinery for the extraction of coal and other bedded materials including trona and salt.
Underground mining. In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata. Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then facilitates the installation of service facilities for such essential activities as
Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper uranium mines can reach 6,500 feet, or 2 kilometers. But those depths are extreme; most top (or bottom) out at about 1,000 feet (300 meters) [sources: Times Wire, ARMZ, Illinois Coal Association ].

Some of the large mining machinery and vehicles are housed in Hope Store. These include underground locomotives, BJD coal cutters, a 1967 NCB Morris ambulance used at Markham Main Colliery, South Yorkshire, and our seventeentonne Dosco Roadheader that was used to cut roadways underground. The Dosco can be seen in action on special demonstration days outside the store
28/11/2018#0183;#32;Twenty percent to 30 percent of mined coal underground is from longwall mining. This is performed by a mechanical cutter that shears coal off from a panel on the seam. The panel being worked on may be up to 800 feet in width and 7,000 feet in length. Mined coal is deposited onto a conveyor that moves the coal to a collection area.
Underground mining loaders: taking the strain. LHDs (Load, Haul and Dump) handle the toughest of underground applications. These mining loaders are highly manoeuvrable and give exceptional productivity. Standard features include, for example, FEAoptimized frames, powerful fuelefficient engines, high breakout forces and ergonomic controls.
