摘要
煤矿采空区积水是威胁矿井安全生产的主要因素之一,对其进行防治具有重要意义。通过对耿村煤矿采空区积水规律的研究,总结出在积水采空区下探放水技术及方法,解决了探水时钻孔塌孔与埋钻问题,使采空区积水顺利放出,确保了掘进和回采工作面安全生产。
The technique and method of gob water exploration and discharge were summarized by study on the rule of gob water-accumulation.The problems of collapse and burying during drilling holes were solved,so as to ensure safe tunneling and coal mining at coal face.
