摘要
针对某矿特厚煤层综采放顶煤工作面回采巷道变形量大、维护困难等问题,采用现场监测工作面回采巷道位移、顶板离层、锚杆(索)受力、煤柱应力等手段,研究8105相邻工作面回采对本工作面回采巷道的扰动作用,探究综放工作面回采巷道的矿压显现规律。
According to tremendous deformation and supporting difficulty in the ultra thick seam fully mechanized top coal carving mining working face＇s mining roadway in some coal mine, using the method of monitoring roadway displacement, roof separation, anchorage force of bolt and stress of coal pillar in mining gateway, this paper studies the influence 8105 adjacent face mining on working face mining roadway, explores the characteristics of the mine pressure appearance law in mining roadway of fully mechanized carving face.
