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。
关键词: 三维电法, 底板注浆, 二极装置, 切片技术, 富水区域
Abstract: Aiming at big mining deep coal mine threatened by high pressure water, the working face need to grouting reconstruction before mining, and the design of drilling generally uniform holes in the face of upper, middle and lower part, this way of designing the drilling has a large workload, low efficiency of faults. Through 3D electrical method for working face detection, delineating the rich water area, analysis the main fracture direction, determine the target area, to focus on grouting target area. When grouting is completed,the effort of grouting requires again to detect by the 3D electrical method ,the weak of grouting need to reinforce the floor, In order to meet safety requirements for mining. Tanking the mine caozhuang’ s face of 101002 threatened by water for example, through 3D electrical method for the face detection and grouting test,the working face was safety mining, the floor didn’t inrush water,this technology has a strong practicability and popularization.
Key words: 3D electrical method, the floor of grouting, pole-pole device, the technology of slice
