摘要
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 the situation of the cross mining underneath 5 soft rock gateways of No 4303 Island fully mechanized caving face in Dongtan Mine, the paper provided a back filling reinforced repair support technology base on the analysis the cross mining gateway support function principle. The certain deformation failure of the cross mining gateway was repaired with good support results.
