摘要
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 floor heave in Fenghui coal mine 15104 tail entry which is affected by mining, by means of numerical simulation and theoretical analysis finds that the main cause of floor heave is the interaction of the adjacent goaf and the insufficient bearing capacity of the coal pillar. Based on this, puts forward the technical scheme. The new scheme can effectively solve the problem of floor heave and has been obtained remarkable economic benefit.
