利用水化学特征识别桑树坪煤矿突水水源

摘要

Finding the water source timely and accurately is the key for solving water bursting problem in mine. The water quality analysis of water samples in groundwater aquifer in a mining area was conducted. The hydro-chemical characteristics of different groundwater aquifers were analyzed using the trilinear chart of Piper. Through comparison of the water bursting place and the hydrogeochemical characteristics, the results indicated that the source of water bursting in mine is Ordovician limestone karst water. The hydrochemical characteristics analysis is a quick method for identification of the source of water bursting.%　　及时准确地找到突水水源，是解决矿井突水问题的关键。通过对桑树坪煤矿主要含水层水样进行常规水质分析，并通过Piper三线图揭示了矿区不同地下水含水层的水化学特征，并通过出水点与背景值的水文地球化学特征对比，正确地判断出了该矿区突水水源为奥灰岩溶水。研究认为，水化学特征分析是一种快速判别突水水源的有效方法。
