摘　　要：如今,矿井企业广泛采用锚杆(索)支护技术控制巷道顶板及围岩的稳定,然而由于地质环境、应力条件的差异性,使得软岩巷道支护技术的设计及实施相对困难,进而造成了软岩巷道支护环境较差的局面。针对龙门塔煤矿9107工作面软岩巷道在掘进过程中出现的顶板及两帮破碎严重的现象,通过理论分析与现场实践相结合的研究方式,采用“锚杆+锚索+金属网”的联合支护方案,对软岩巷道的支护参数进行了设计与应用。现场实测数据显示,在巷道开挖过程中,顶板最大下沉量为96 mm,两帮最大移近量为135 mm,围岩变形得到了有效地控制,整体支护效果良好。Mine enterprises widely use the technology of bolting(cable)support to control the stability of roadway roof and surrounding rock.However,due to the difference of geological environment and stress conditions,the design and implementation of soft rock roadway support technology is relatively difficult,which results in the poor environment of soft rock roadway support.Aiming at the serious fracture of the roof and two sides of the 9107 working face soft rock roadway in Longmenta mine,this paper designs and applies the supporting parameters of the soft rock roadway by combining theoretical analysis with field practice and adopting the combined support scheme of“anchor rod+anchor cable+metal mesh”.The actual monitoring results show that the maximum subsidence of the roof is 96 mm and the maximum displacement of the two sides is 135 mm,which effectively controls the deformation of the surrounding rock of roadway with good overall supporting effect.
