摘要
通过分析某矿运输顺槽支护上存在的问题及顺槽失稳原因,对运输顺槽支护进行优化并与原有支护方案进行数值模拟分析,比较两者之间的围岩应力,并进行工业性实验。通过实验结果分析得出优化方案极其有效,为类似条件下巷道围岩支护提供了参考。
Based on the analysis of the problems existing in the transportation gateway support of a mine and the reasons for the instability of the gateway,the transportation gateway support is optimized and analyzed by numerical simulation with the original support scheme,and the surrounding rock stress between them is compared,and an industrial experiment is carried out.Through the analysis of the two experimental results,it is concluded that the optimization scheme is extremely effective,which provides a successful case for surrounding rock support under similar conditions.
