摘要
通过对巷道支护围岩特征及受力情况分析,在理论指导下结合巷道实际压力及服务年限对百善煤矿巷道进行差异化支护,支护期间进行了密切跟踪和观察,取得了良好的效果。
On the basis of support theory and combined with the actual pressure situation and service life of roadway,through analyzing roadway rock characteristics and stress state,the differential support was used in Baishan Coal Mine.The roadway situation was closely tracked and observed after support,and it showed that good support effect was got.
