及时准确判断矿井突水成因,查找突水水源,是解决和预防突水灾害的关键. 以某矿东钻机在正常钻进过程中突发井喷的现象为研究背景,通过现场测定出水流量、水温、pH值、电导率,以及室内水化学分析,综合流量、pH值动态分析和水化学分析,初步对井喷钻孔进行水源分析;通过对比分析,依次得到不同分析方法下最有可能的出水含水层,采用集合相交的方法综合分析各可能出水含水层,初步判断出水水源为太原组灰岩含水层.

To timely and accurately judge the cause of mine water inrush and find out the water inrush source are the key to solve and prevent water inrush disaster. In this paper, preliminary analysis was made on the water source of the blowout borehole by taking the sudden blowout phenomenon in normal drilling process of the east drilling machine in a mine as study background and through the site measurement of water flow, temperature, pH value and conductivity and indoor hydro-chemical analysis of water samples and the dynamic and hydro-chemical analysis of the integrated water flow and pH value. Through comparison and analysis, the most possible water inrush aquifer was successively obtained by different analysis method, then comprehensive analysis was made on each possible water inrush aquifer with set intersection method, and the preliminarily judgment was that the water inrush source was the Taiyuan limestone aquifer.
