摘　　要：为有效解决近距离煤层孤岛工作面冲击矿压问题,以山西寿阳潞阳瑞龙煤业有限公司150108工作面为背景,采用理论分析、现场试验方法,对150108工作面冲击矿压危险性进行了评价,确定150108工作面无冲击危险,综合各类回采因素,在工作面内划分了3个重点监测区域,并采用钻屑法和施工大孔径钻孔卸压方法对重点区域进行管控。根据工作面回采情况,回采期间未出现冲击矿压现象。In order to effectively solve the problem of rock burst at the isolated island working face in close coal seams,based on the conditions of the 150108 working face in Shanxi Shouyang Luyang Ruilong Coal Industry Co.,Ltd.,the risk of rock burst at the 150108 working face is evaluated by using theoretical analysis and field test methods.It is determined that there is no rock burst at the 150108 working face,and three key monitoring areas are divided in the working face by integrating all kinds of mining factors,In addition,the drilling cuttings method and the pressure relief method of construction large bore hole are used to control the key areas.According to the mining conditions of the working face,there is no rock burst during mining.
