摘　　要：某煤矿井田范围内的可采煤层相对较多,本身也属于近距离的煤层群。所有近距离的煤层群在有效地开采之后,其承受的压力会不断地变化,进而形成一种有效的集中区。专业人员应该在开采的过程中选择一种合理的支护方式。本文以某煤矿为背景来分析巷道矿压规律。从实验的结果来看,在一般支护条件下,巷道变形和松动的范围并不大,一般可以让巷道更加稳定地运行。There are relatively many minable coal seams in a coal mine field,and they also belong to short-distance coal seam groups.After all the short-distance coal seams are effectively mined,the pressure they bear will change constantly,thus forming an effective concentrated area.Professionals should choose a reasonable support method in the process of mining.Based on a coal mine,this paper analyzes the law of roadway ground pressure.Seen from the experimental results,under the general supporting conditions,the deformation and looseness of the roadway are not large,which can generally make the roadway run more stably.
