注浆充填采煤技术在杨柳煤矿的应用

Application of Grouting and Filling Mining Technology in Yangliu Coal Mine

杨柳煤矿1074工作面回采影响地面大辛家村庄建筑物,迁村开采投资巨大、经济风险高,经研究决定采用注浆充填置换采煤技术进行村庄下煤炭开采。通过采取合理设计注浆钻孔、采用高性能的注浆材料和合理控制工作面的回采速度等措施,实现了不迁村采煤。

The mining of the 1074 face of Yangliu Coal Mine affects the building of Daxinjia village on the ground.There are huge investment and high economic risk in moving villages to exploit.After research,it is decided to adopt the grouting filling replacement mining technology for coal mining under the village.By adopting reasonable design grouting drilling,adopting high performance grouting material and reasonably controlling the mining speed of working face,coal mining without moving villages is realized.
