底板注浆加固技术在盘区巷道中的应用
|
摘要
以某传统矿区盘区巷道底鼓治理为主要工程背景,研究了巷道底鼓机理与注浆加固技术,并对注浆参数影响因素进行了分析;采用UDEC数值软件对底板注浆加固效果进行了分析,同时对现场注浆段围岩进行了位移监测。研究结果表明,采用底板注浆技术能够很好地控制巷道的整体变形,减少了巷道的底鼓量,保持了巷道的整体稳定。
The main engineering background of roadway bottom heave in a traditional mining area is studied, the mechanism of floor heave and grouting reinforcement technique are studied, and the influence factors of grouting parameters are analyzed. UDEC numerical software is used to analyze the reinforcement effect of the bottom plate grouting, and the displacement monitoring of the surrounding rock of the grouting section is carried out. The results show that the slab grouting technique can effectively control deformation of roadway′ s overall, reduced the amount of floor heave of roadway,maintain the overall stability of the roadway.
