基于同位素方法的矿井突水水源定量分析研究

Quantitative Analysis of Mine Water Inrush Using Isotope Method

在分析山西龙泉煤矿水文地质特征及工作面突水特征的的基础上,研究了矿区各类水体的水化学及环境同位素特征,确定了01工作面突水水源为太灰、奥灰混合水,利用同位素方法定量计算了太灰水占工作面突水来源的46%,而奥灰水占54%。研究结果表明:应用同位素方法能定量、准确判断出矿井突水的主要来源,可为制订有效的防治水措施提供科学依据。

Based on the analysis of hydrogeological characteristics and water inrush characteristics of Longquan Coal Mine in Shanxi,the hydrochemistry and environmental isotope characteristics of various water bodies in the mining area are studied.It is determined that the source of the 01 working face water inrush is mixed water of Taiyuan Formation limestone aquifer and Ordovician limestone aquifer.The isotope method is used for quantitative calculation,showing that the Taiyuan Formation limestone aquifer accounts for 46%of the source water inrush from the working face,while the Ordovician limestone aquifer accounts for 54%.The research results showed that,the isotope method can determine the main source of mine water inrush quantitatively and accurately,and provide a scientific basis for the development of effective water control measures.
