As of 2015 the Anthracite Region produced total of 4,614,391 tons of coal, predominately from surface coal mines. Bituminous Coal. Bituminous mining operations are active in 21 counties in the southwest region of Pennsylvania and is the most abundant coal found in our state. Its primary uses are for electricity generation and metal production.
surface coal mining operations are so conducted as to protect the environment, and to strike a balance between protection of the environment and agricultural productivity and the Nations need for coal as an essential source of energy. 30 U.S.C. 1202d, f.
In summation, the selection of equipment to meet the mining requirements is essential in a competitive operation such as coal mining. The BWE-XPS System offers a new solution in the United States for the 1000 lateral transfer of overburden at a significant time and cost reduction over cyclic methods.
