Design Aspects in Multiple-seam Mining: Case Studies.
Paper in Proceeds of the 9th International Conf on Ground Control in Mng WVU PP 12-21 :12-21
Developing a coal seam that has been influenced by previous mining in seams either above or below can result in severe ground control problems. In many instances, interactions between operations are inevitable, but improvements in ground stability can usually be achieved by predicting potential problem areas in advance and adjusting the mining plans accordingly. This report investigates four case studies involving interactions between operations that used both room-and-pillar and longwall mining methods. In each case, geologic and mine design parameters are addressed, and those parameters found critical to the interaction are further defined in relation to observed ground problems.
