摘　　要：以曹庄煤矿受水威胁工作面101002为例,利用三维电法对工作面进行了探查,圈定了富水区,分析主裂隙发育方向,确定了靶区,对靶区采取重点注浆,通过三维电法检测注浆效果,并对注浆薄弱区进一步注浆加固底板,工作面底板经注浆后,原地层富水区域发生了变化,使工作面达到了安全回采的要求。Based on the 101002 working face threatened by water in Caozhuang Coal Mine,the 3D electrical method was applied for working face detection,the rich water area was delineated,and the main fracture direction was analyzed,determining the target area,to focus on the target area grouting. The grouting effect was detected using 3D electrical method,and the weak area was reinforced through floor grouting,the original water rich area in stratum was changed,enabling the safe mining of the working face.
