义棠青云煤矿副立井井壁局部破损协同加固技术

Coordinated reinforcement technology for local damage of auxiliary shaft wall in Yitang Qingyun Coal Mine

采用“壁后注浆封堵涌水点,挖补置换破损位置井壁混凝土”协同加固技术,对义棠青云煤矿副立井井壁局部破损部位进行了修复。该技术实现了井壁破损部位的修复,在不影响煤矿正常生产的前提下消除了安全隐患。此经验可供类似工程设计及施工参考。

The local damaged part of the shaft wall of Yitang Qingyun Coal Mine was repaired by using the coordinated reinforcement technology of"plugging the water gushing point by grouting behind shaft,dredging and replacing the damaged part of the shaft wall".The technology realized the repair of the damaged part of the shaft wall and eliminated the safety hazard without affecting the normal production of the coal mine.This experience could be used as reference for similar engineering design and construction.
