圈定法煤矿井下采空区探水技术研究

Technology Research on Determination Method in Exploring Water of Coal Mine Goaf

传统的以密集钻孔布置的方法探查采空区积水的探放水技术有不便组织实施的实际问题。本文论述了通过多向钻孔的交汇,以合理选择钻探地点、钻孔方向、钻孔深度的方法,进而圈定一次掘进安全区域的圈定法探放水方法。这种探放水方法具有施工组织简单、探水作业量小、探水有效性高的特点。

n the traditional dense borehole layout method detection and drainage technology of exploring goaf seeper has the practical problems that the organization and implementation is inconvenience.This paper discusses the reasonable selecting drilling sites,the direction of drilling,drilling depth by multidirectional drilling convergence method,and delimit a driving safety area delimitation exploration and drainage water method.The exploration and drainage water method has the characteristics that construction organization is simple,exploring water amount is small,water exploration effectiveness is high.
