Underground mining involves opening one or more portals or shafts into the earth that follow or intercept coal seams that are too deep for surface mining methods. Two main methods of underground mining are practiced in Pennsylvania Room-and-Pillar Generally used for seams that are relatively flat or gently dipping. As the room is mined, large pillars of coal are left
Read MoreOf the many different methods of deep coal mining, the most productive is coal face retreat mining, also known as longwall mining. This involves driving two parallel roadways into the coal seam, typically 280 to 350 metres apart and up to 3,000 metres in length, before connecting both roadways to create a panel of coal.

Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. The pits are parallel and adjacent to each other. Strip mining is fundamentally different from contour or area mining on how the overburden is displaced, called spoil handling. Jan 05, 2021 By analyzing rockburst accidents, comparing those that occurred in deep and shallow coal seams, it was found that rockburst in the DCG is more likely accompanied by features of high-stress, large dip angle, hard thick roof, unstable coal seam, frequent and strong disturbances, unreasonable mining methods and insufficient protection measures.
Read MoreA. 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.
