摘　　要：针对某煤矿的特厚煤层厚度变化较大且具有一定的倾角,造成开采困难的问题,依据煤层的赋存条件,分析分层开采及综放开采的可行性,对开采工艺的技术可行性及生产成本进行分析,确定长壁放顶煤综采方式适用于特厚煤层的开采工艺。The thickness of the coal seam varies greatly and has a certain inclination angle,which causes difficulties in mining.Based on the occurrence conditions of the coal seam,the feasibility of layered mining and fully mechanized top coal caving mining was introduced,and the technical feasibility and production cost of mining were analyzed.It was determined that the longwall top-coal caving comprehensive mining method is suitable for the mining process of ultra-thick coal seams.
