摘要
通过对郭屯煤矿中央泵房实际情况的调查与分析,阐述了巷道破坏机理,根据巷道特点,采用锚网索喷一次支护、锚注二次支护的技术方案进行加固支护,并通过数值模拟分析得出最佳二次支护时机,取得了良好的技术经济效果。对于类似条件下的巷道支护具有一定的参考价值。
Through the investigation and analysis for practical situation of pump house in Guo - Tun Mine, Explain the roadway destruction mechanism, according to the characteristics of roadway, use bolting - net - spray as the first support, bolt - net - injection rein- forcement as second support, and get the best chance for second support through Numerical Simulation, acquire good technical and economic effect, have the certain reference value to the similar conditions for roadway support.
