为解决丰汇煤矿受采动影响的15104轨顺底鼓问题,通过数值模拟结合理论分析的方法得出底鼓主要原因是受到相邻采空区影响和煤柱承载能力不足的共同作用。并据此提出具有针对性的支护方案,现场监测表明新方案有效地解决了巷道底鼓问题,经济效益显著。
In order to solve the problem of 15104 track boring kick drum affected by mining in Fenghui coal mine, the main reason of kick drum is obtained by numerical simulation combined with theoretical analysis. It is caused by the influence of adjacent goaf and the insufficient load bearing capacity of coal pillar. Based on this, a targeted support scheme is put forward. On-site monitoring shows that the new scheme effectively solves the problem of tunnel bottom drum and has obvious economic benefits.
