摘要
为解决山西宁武榆树坡煤业有限公司5109工作面底板突水难题,采用现场调研手段研究了5109工作面底板突水防治技术,通过现场钻探确定了注浆改造的区域治理技术方案。工作面底板综合处理有效填充了围岩裂隙,堵塞了导水通道,保障了煤层开采的安全进行。
In order to solve the problem of floor water inrush of 5109 working face of Yushupo Coal Industry Co.,Ltd.,field investigation methods were employed to study prevention and control technology,and the regional management technology programme of grouting modification was determined through on-site drilling.Through the comprehensive treatment of the working face floor,the fissures in the surrounding rock were effectively filled and the water-conducting channels were blocked,which ensured the safety of coal seam mining.
