Coal mining - Coal mining - 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 …
involved in making such an estimate. The exact quantity of coal resources is not known. We cannot predict what improvements will be made in mining technology that would allow the recovery of more of the coal than is currently achieved. We cannot evaluate with certainty what tolerance coal consumers might have for using coal of lower quality than is

This process is primarily aimed at recovering methane for commercial use in its own right and as such is not strictly part of coal mining. It is possible however, and in some cases is occurring, for a coal mining operation to carry out the same process primarily to remove the gas to assist later coal mining operations.

Jan 27, 2015 COAL MINE FATALITY – On Tuesday, October 7, 2014, a 31-year-old utility worker, with 13 years of mining experience, was killed after he crawled 37 feet into an entry mined with a highwall mining machine to retrieve a broken cutter-head-chain from the mining machine. A rock, 8 feet wide, 6 feet long, and 16 inches thick fell on him.
3 The narrow economic base of many coal mining regions requires careful mitiga-tion of coal mine closure impacts. Coal mining is often concentrated in regions far from major population and economic centers where alternative employment pros-pects may be found . As a result, “mono-industry” coal towns and regions face mul-
The first way in which proposed mining projects differ is the proposed method of moving or excavating the overburden. What follows are brief descriptions of the most common methods. 220.127.116.11 Open-pit mining Open-pit mining is a type of strip mining in which the ore deposit extends very deep in the ground,
