摘　　要：为治理大断面、高应力软岩巷道底鼓问题,提出了“壁后注浆+组合锚索”的巷道围岩支护方案,并在平煤六矿北二进风井中央变电所进行了实际应用。该支护方案能够有效控制巷道表面围岩变形,显著提高巷道支护的自承载能力。结果表明:前20 d巷道表面变形剧烈,40 d后巷道表面位移基本趋于水平,巷道围岩变形得到了很好的控制。In order to solve the problem of floor heave in large section and high stress soft rock roadway,the roadway surrounding rock support scheme of"back wall grouting+combined anchor cable"is proposed and applied in the central substation of North No.2 air inlet shaft of Pingmei No.6 Mine.The support scheme can effectively control the deformation of surrounding rock on the roadway surface and significantly improve the self-bearing capacity of roadway support.The results show that the roadway surface deformation is severe in the first 20 days,the roadway surface displacement basically tends to be horizontal after 40 days,and the roadway surrounding rock deformation has been well controlled.
