摘要
基于工作面运输顺槽围岩渗漏、顶板冒落问题,通过分析围岩力学性能及裂隙构造,结合注浆加固技术对运输顺槽进行二次加固.经过现场监测,发现注浆效果较好,60d监测周期巷道顶底板及两帮移近量仅为15cm、20 cm,控制效果明显.
Abstract
Based on the current situation of seepage and roof fall of the peripheral rock in the transport roadway of the working face,this paper analysed the mechanical properties of the peripheral rock and the fissure structure,and carried out secondary reinforcement of the transport roadway by combining the grouting and reinforcement technology.After on-site monitoring of the grouting effect is good,60 d monitoring cycle of the roadway top and bottom plate and two gangs of only 15 cm,20 cm,the control effect is obvious.
