摘要
为了解决软弱复合顶板巷道变形严重的问题,通过机理分析并结合数值模拟研究了巷道的应力分布情况,并提出锚索注浆加固的方案.通过布置表面位移监测表对加固效果进行分析,发现支护后的围岩变形量明显减小,较好地维护了巷道的稳定性,为矿山安全生产提供借鉴.
In order to solve the serious deformation problem of weak composite roof roadway, this paper studies the stress distribution of roadway by mechanism analysis combined with numerical simulation, and puts forward the reinforcement scheme of anchor cable grouting. Through the analysis of the reinforcement effect by arranging the surface displacement monitoring table, it is found that the deformation of surrounding rock after supporting is obviously reduced, and the stability of roadway is well maintained. to provide reference for mine safety production.
