摘要
结合顾桥矿中央变电所硐室变形破坏的实际情况,分析了硐室变形破坏的主要原因,提出了硐室全断面注浆加固、底板采用深孔锚索注浆加固的修复方案;通过近2个月的现场观测表明该治理措施加固软弱破碎、穿越断层巷道的效果较为明显。
Combined with the actual situation of the central mine substation chamber deformation and failure in Guqiao Mine,the main reason of the deformation and failure of chamber is analyzed,the repair program with whole section grouting reinforcement of chamber and deep cable grouting on the bottom is put forward.After nearly two month of field observations,the governance measures can effectively reinforce the weak broken chamber and pass through the fault roadway.
