摘　　要：针对余吾煤矿工作面末采期,产生的动压对邻近采区大巷的破坏。通过在N1101工作面停采线附近采用水力压裂卸压,可有效破坏顶板完整性,弱化力学性能,从而降低矿压显现,使动压系数减小,有效降低动压对大巷带来的破坏,降低巷道维护成本,取得较好效果,为其他受动压影响巷道提供技术支撑。According to the damage of dynamic pressure in the last mining period of the working face in Yuwu Coal Mine to the main roadway in the adjacent mining area,using hydraulic fracturing to relieve pressure near the stop line of N1101 working face,the roof integrity can be effectively destroyed,the mechanical properties can be weakened,thus the strata pressure appearance can be reduced,the dynamic pressure coefficient can be reduced,and the damage caused by the dynamic pressure to the main roadway can be effectively reduced,reduce the cost of roadway maintenance,achieved good results for other affected by dynamic pressure roadway to provide technical support.
