摘要
针对深井复合顶板回采巷道埋深大、地质构造复杂,构造应力及矿压显现,从现在巷道的支护理论出发,结合李雅庄矿在深部巷道不同岩性下松动范围方面,分析了锚索锚杆支护巷道、加固围岩的作用原理及施工技术,取得了很好的技术经济效益。
In accordance with geologic structure complexity,roadway bury deeply,structure stress and mine pressure showing,combining roadway support theory with rock rapping range,analyses the operation principle and constructive technology of bolting support and reinforce surround rock,it has achieved the better technique and economic results.
