摘要
伯方煤矿3中11综放面煤层裂隙发育,架前冒顶频繁。该矿在分析冒顶原因的基础上,采取针对性预防处理措施及实施破碎围岩柯地散注浆加固技术,取得了显著的技术经济效益。
The coal seams are fractured at NO.11 fully mechanized caving face in Baifang Coal Mine.The roof frequently falls before supports.Based on analysis on roof falling,the preventive measures and technology of grouting reinforcement for the fractured surrounding rock are proposed,and the great ecnomic benefits are abtained.
