岩层探测记录仪在顶板探测中的应用

    Application of Strata Detector Recorder in Roof Detection

    • 摘要: 针对陈蛮庄矿破碎顶板影响工作面正常生产的问题,运用YJT 20型岩层探测记录仪,对山东肥矿集团陈蛮庄矿3206工作面轨道巷顶板进行了全面观测。探测并分析了3206工作面轨道巷超前支承压力影响段、正常段、地质构造影响段以及联巷交汇处的顶板离层位置和裂隙发育情况。探测结果表明:超前支承压力及地质构造对轨道巷顶板的裂隙发育状态有较大影响;联巷交汇处的顶板离层现象严重,需加强支护。

       

      Abstract: Aiming at problem in Chenmanzhuang Coal Mine that fractured roof affects the normal production of working face, using YJT 20 strata detector recorder, we conducted comprehensive observation to the roof of track roadway in Chenmanzhuang Coal Mine 3206 working face of Shandong Feicheng Group. Roof separation position and the development of fracture of the abutment pressure influence section, normal section, geological structure influence section of track roadway and crossheading in 3206 working face has been detected and analyzed. The results show that lead abutment pressure and geological structure have influence on the developing state of fracture in track roadway roof; roof separation was severe at the intersection of track roadway and crossheading.
