反射槽波在工作面内多条平行断层探测中的研究与应用

Research and Application of Reflected In-seam Wave Detection Technology in Detection of Multiple Parallel Faults in Working Face

目前,矿井小构造对煤炭开采的影响越来越突出,断层是矿井小构造的主要类型,对矿井安全高效开采造成严重影响。探讨了反射槽波探测技术在单条巷道同侧2条走向断层中的研究与应用情况,建立了煤层中含断层的二维及三维数值模型,证明了该方法的可行性,并利用该技术在阳煤集团长沟煤矿15110工作面进行断层探测,取得了良好的应用效果。

At present, the impact of small mine structures on coal mining is becoming more and more prominent. Faults are the main type of small structures in mines, which have a serious impact on the safe and efficient mining of mines. The research and application of reflective in-seam wave detection technology in two strike faults on the same side of a single roadway are discussed. Two-dimensional and three-dimensional numerical models of faults in coal seams are established, which proves the feasibility of the method. And using this technology to carry out fault detection in the 15110 working face of Changgou coal mine of Yangmei group, and achieved good application results.
