摘　　要：葛店煤矿N31采区有两层可采煤层,距离很近,煤层中间岩层平均厚度为2.6 m。葛店煤矿采取了上下两层煤同时开采的方式,实现了安全回采,提高了煤炭回收率,带来显著的经济效益。Two coal seams are located in N31 block in Gedian Coal Mine. Their distance is greatly short. The rock distance between two coal seams is 2.6m. The style of two coal seams being mining at the same time is adopted. Stoping safely is accomplished, the coal yield is improved and rather than notability economy benefit is achieved.
