摘要
根据不同含水层在水化学特征上的差异,提出基于水化学原理判别矿井涌(突)水水源的混合水判识模型。以开滦荆各庄矿为例,通过绘制Piper三线图判断待识别水样来源,运用PHREEQC软件建立矿井水源混合模型,并以6大常规离子和pH值为识别因子,提出了根据欧氏距离计算结果判断矿井混合水突水水源的模型。结果表明,通过Piper三线图与欧氏距离结合的模型判别,涌水水源的水80%来自K6—12煤砂岩裂隙含水层(Ⅲ),20%来自9煤—7煤砂岩裂隙含水层(Ⅳ),经与实际化验结果对比,该结果符合实际。
This paper proposes a model based on the principle of hydrochemistry that there are differences in hydrochemical characteristics between different aquifers to identify the source of mixed water-inrush.Taking Jinggezhuang Mine in Kailuan as an example,the source of the water sample is identified by drawing Piper’s three-line diagram.The mixed model of mine water source is established using PHREEQC software,which takes six conventional ions and pH value as the identification factors,and it is proposed to judge the water source of the mixed water-inrush according to the calculation result of Euclidean distance.Theresults showthat combining Piper three-line diagram with Euclidean distance is an accurate and feasible model to identify thesource of mixed water-inrush.
