摘要
桃园煤矿10煤层具有Ⅱ类自燃发火倾向性,工作面倾角大,采用传统的黄泥浆液灌浆易堵塞管路,采用JDAQ-1型泥浆增稠防堵添加剂进行预防性灌浆解决了这一难题,在大倾角工作面采空区预防性灌浆中有着实际的推广应用价值。
Taoyuan Mine 10coal seams with class Ⅱ spontaneous combustion tendency,angle of the face,using the traditional slurry grouting is easy to plug the pipeline,using JDAQ-1 type slurry thickening plugging prevention additives for preventive grouting to solve this problem,in the large dip angle working face goaf preventive grouting with actual application value.
