近年来,喷锚支护在地下工程中大量推广。但由于对这种支护产生的渗漏尚无成熟治理方案,而影响着这一新技术在对防水防潮有较高要求的工程中推广应用。我矿在治理采用喷锚支护的卷扬机及配电硐室的渗漏中,试用了胶泥塞漏及喷射防水层堵渗的综合治理方法,取得了满意的效果。现介绍如下: 我矿沃溪坑口二号付井卷扬机及配电硐室位于距地表40米的板岩岩层内(f=4～5)。断层,节理
In recent years, spray anchor support a large number of underground projects in the promotion. However, due to the leakage of such support there is no mature treatment program, which affects the new technology in the waterproofing of the higher requirements of the project to promote the use of. I mine in the use of spray-anchor support hoist and distribution room leakage, the trial of the cement plug leakage and jetting waterproof layer of integrated management methods, and achieved satisfactory results. Here is a brief introduction: My mine Wo Xioukou No. 2 pay hoist and power distribution chamber is located within 40 meters of the slate rock formation (f = 4 ~ 5). Faults, joints
