摘要
针对阿舍勒铜矿650m中段采场直接顶板不稳固,矿岩接触带地质条件复杂等问题,开展了长锚索、喷锚网和注浆多技术联合支护的试验研究,取得了良好的效果;同时就采场地压及其支护等相关问题提出了处理办法。
In allusion to the problem of the unstabilty of the direct back of the 650M middle part of ASHELE copper mine and the complex geologic condition of the contiguity zone of mine rock, the experimentation and research of long anchor cable, spray anchor net and multi-technology combined bolting of slurry poring were developed and a preferably effect has been gained. In the meantime the disposal way of the ground pressure and its bolting has been brought forward.
