摘　　要：随着煤矿开采深度的不断增大,围岩地应力愈来愈大,巷道经常出现顶板下沉,脱落、两帮收缩、底板鼓起等变形破坏现象,变形破坏严重时,甚至巷道无法使用,严重影响安全生产。河南煤化集团五凤煤业公司五凤矿中二采区运输大巷在过软岩段施工中,巷道掘支后过一段时间,便出现喷层开裂、脱皮掉块、底板鼓起等破坏现象。为此,我们在软岩巷道锚网喷支护的基础上增加了锚索支护,提高了支护效果和巷道稳定性。with the increase of coal mining depth, surrounding rock stress more and more big, often appear in the roadway roof sinks, fall off, two help shrink and floor, such as up of deformation and failure of the phenomenon, deformation and failure of the seri- ous, even unable to use the roadway, the serious influence the safety in production. Henan five chicken coal company project group five chicken mine in two mining DaHang transportation in soft rock in the construction period, to dig a roadway after a long time, they appear spray layer crack, peeling DiaoKuai up and floor, damaged phenomenon, therefore, we in the soft rock tunnel spray the anchor net supporting based on the increase bolt-cable and improve the roadway supporting effect and stability.
