摘要
为解决陕北某矿二、四盘区主运巷支护强度大,支护体利用效率不高的问题,以岩石力学实验及围岩松动圈测试的结果为依据,采用松动圈理论及极限平衡区理论进行支护方式的优化设计。经现场工业性试验,得到了理想支护效果并取得良好的经济效益。
In order to solve the problems of supporting difficulty and low supporting efficiency in main transport roadway of No. 2 and No. 4 panel in a mine of northern Shaanxi,the broken rock zone theory and limit equilibrium theory were adopted the optimization design of the support mode design based on the rock mechanics test and surrounding rock loose test. The field industrial test shows that the good supporting effect and economic benefits was obtained.
