以贺西煤矿近距离煤层3号和4号煤层工作实际条件为背景,通过采用数值模拟及现场实测的方法对近距离煤层同采条件下回采巷道的合理错距进行了研究.研究结果表明针对贺西煤矿的实际条件回采巷道应外错布置9 m,才能保证在工作面回采中巷道的稳定性与安全性.现场实测也进一步验证了在巷道外错布置9 m的条件下,2410工作面的顶板下沉量最大为156 mm,两帮最大移近量为142 mm,说明回采巷道围岩得到了很好的控制.研究结果也为其他类似条件下的近距离煤层回采巷道布置提供了指导.“,”Taking the actual working conditions of He Xi close distance coal seam no. 3 and no. 4 coal seam as the background, we study the reasonable separation of mining roadway that under the condition of close distance coal seam mining through the numerical simulation and field measurement method.Research results show that according to the actual conditions of He Xi coal mine roadway, outside fault should decorate 9 m, ensure that mining roadway stability and security. Field measurement is also further verified under the condition of external fault of roadway layout 9 m, 2410 working face roof subsidence quantity is 156 mm, maximum two maximum nearer to 142 mm, of gateways that are well controlled. The results for other similar under the condition of close distance coal seam mining layout provides guidance.
