Modern underground coal-mining methods can be classified into four distinct categories: room-and-pillar, longwall, shortwall, and thick-seam. Room-and-pillar mining. In this method, a number of parallel entries are driven into the coal seam. Get Price
2020/9/11Additionally, exploration drilling is used to identify or confirm the location of faults, folds, dikes, sills, and other geologic features that may influence how the coal is ultimately mined. As mining progresses from the initial exploration phase to the latter stages of exploration and into production, a higher level of detail about the site's subsurface is required.
2020/9/11Longwall mining is an automated form of underground coal mining characterized by high recovery and extraction rates, feasible only in relatively flat-lying, thick, and uniform coal beds. A high-powered cutting machine (the shearer) is passed across the exposed face of coal, shearing away broken coal, which is continuously hauled away by a floor-level conveyor system ( Figure E.2 ).
