摘 要:干河煤矿结合工程实践,采用水力压裂切顶卸压+邻巷高预应力锚索补强+小煤柱护水平大巷+分区分段监测技术等综合手段,减弱回采超前及邻巷煤柱支承压力影响,并提前在邻巷施工高预应力锚索补强控制巷道围岩,帮缩底鼓量、帮缩底鼓范围大幅降低,为工作面快捷高效安全生产创造条件。Combined with the engineering practice,the author proposes the comprehensive measures of hydraulic-fracturing and roof-cutting-and-pressure-relief,high prestressed anchor-cable reinforcement in adjacent lanes,horizontal lane protection by small coal pillar and partition-section monitoring technology,which can reduce the influence of advanced mining and the abutment pressure of coal pllars in adjacent roadway,pre-controllthe surrounding rock,and reduce the floor heave volume and range of sides shrink greatly,creating conditions for the fast and efficient and safe production of the working face.
