摘　　要：和顺一缘煤业猴车巷为料石砌碹巷道,局部区域碹后存在大面积空洞,围岩裂隙发育充分,矿压显现明显,巷道变形严重。为保证巷道的安全使用,采用注浆加锚索联合支护方法对巷道进行综合治理。注浆加固后,其强度有所提高,提高结构稳定性和承载能力,巷道顶板活动明显减缓,保证了巷道安全使用。Houche Lane in Hesun Yiyuan Coal Industry is a masonry roadway.There are large areas of cavities behind the arch in some areas.The surrounding rock fissures are fully developed,the mine pressure is obvious,and the roadway deformation is serious.In order to ensure the safe use of the tunnel,the combined support method of grouting and anchor cable is used for the comprehensive treatment of the tunnel.After grouting reinforcement,its strength has been improved,the structural stability and bearing capacity have been improved,the roof activity of the roadway has been slowed down obviously,and the safe use of the roadway has been ensured.
