摘要
基于塔山煤矿8108工作面回采期间出现较大矿压显现,联通工作面的材料巷和运输巷矿压显现更为明显,导致顶板离层、底板底鼓等现象。采用工作面留设条带顶煤柱的方法以后,有效控制了工作面压力,来压强度相对减弱,达到了安全生产的目的。
Based on large mining pressure in 8108 working face recovery of Tashan Mine, mining pressure in materials roadway and transportation roadway combined working face was more obvious, which led to roof separation and floor heave. Working face with band top coal pillar was adopted to control the working face pressure, pressure strength weakened, which achieved the purpose of safe mining.
