摘要
通过分析王楼煤矿二采区行人下山巷道围岩应力分布和巷道围岩破坏情况,采用锚杆端部特殊处理的高强高预紧力锚杆,并使用"亲泥性注浆材料"对巷道进行全断面分两次注浆,有效控制了巷道围岩变形。
By analyzing the king building coal mining area two pedestrians mountain tunnel surrounding rock stress distribution and damage of roadway surrounding rock,adopt the anchor end special processing with high strength and high pre-tightening force of anchor,and use the ＂kiss of mud grouting material＂ ＂two whole section grouting was carried out on the roadway,effectively control the deformation of surrounding rock of roadway.
