根据东滩煤矿4303“孤岛”综放工作面跨采下部5条软岩巷道的情况,在分析跨采巷道支护作用原理的基础上,提出了架后充填加固修复支护技术,并针对跨采巷道的具体变形破坏状况进行了实施,收到了较好的支护效果。
According to the situation of 5 soft rock tunnels across the lower part of 4303 “Gudao ” fully mechanized top coal caving face in Dongtan Coal Mine, based on the analysis of the action principle of roadway support in cross over mining, the technology of backfill reinforcement and restoration support is put forward. Aiming at the concrete deformation and damage situation of cross-mining roadway, the implementation has been carried out, and the better support effect has been received.
