摘要
针对大水头煤矿西二采区运输大巷锚网喷索联合支护技术效果差,结合西二采区运输大巷围岩松软破碎,遇水膨胀的特性,对西二采区运输大巷采用锚注支护技术试验,进行二次补强加固围岩,取得了较好技术效果和经济效益。
Aimed at shotcrete anchor combined support technical poor effect of Xi^r Transport Tunnel in Dashuitou Coal Mine, the char- acteristic of the mining area is combined with surrounding rock soft broken and water expansion, it used bolting and grouting technology test in Xier transport tunnel ,and made secondary reinforcement surrounding rock ,and it achieved good technical results and economic benefits.
