摘　　要：了解煤炭开采驱动下矿井各含水层化学成分及连通性的变化,建立矿井水源快速识别体系,对保护研究区地下水资源和安全生产具有重要意义。通过常规元素数值特征分析、聚类分析以及不同含水层的氘和氚同位素追踪,确定了各含水层的地下水化学特征和水力联系,建立常规水化学成分Piper、Durov识别图和氘氚同位素识别图3个识别图,实现了对各含水层水源的快速识别。结果表明:研究区地下水补给的主要来源是大气降水,在煤矿开采的驱动下,形成了局部地下水系统,改变了局部地下水循环模式,根据水化学离子特征的差异以及氘和氚同位素的差异,建立了3个识别图,确定了西曲煤矿不同含水层的突水来源,并提出了针对性的突水解决方案。Understanding the changes in chemical composition and connectivity of various aquifers in river mines in arid-semi-arid zones driven by coal mining,and establishing a rapid identification system of water sources in river mines are of great significance for the protection of groundwater resources and safe production in the study area.Through numerical characterization of conventional elements,cluster analysis,and deuterium and tritium isotope tracing in different aquifers,the groundwater chemical characteristics and hydraulic connectivity of each aquifer were determined,and three identification maps,namely,conventional water chemical composition Piper,Durov identification map,and deuterium and tritium isotope identification map,were established to realize the rapid identification of water sources from each aquifer.The results show that:the main source of groundwater recharge in the study area is atmospheric precipitation,and driven by coal mining,the local groundwater system is formed,which changes the local groundwater circulation pattern.Based on the differences in the characteristics of hydrochemical ions as well as deuterium and tritium isotopes,three identification diagrams are established to identify the sources of water breakout in different aquifers of Xiqu Coal Mine,and targeted solutions for the breakout are proposed.
