摘　　要：地下水环境问题会导致可利用的地下水资源减少、地下水环境的恶化,从而对人类生活和环境造成严重影响。采用资料收集、开展水文地质调查、评价分析等方法,查明研究区地下水水文地质条件变化特征和矿区水文地质特征,分析地下水环境产生影响的各种因素。研究表明,由于煤矿开采导致地下水水位下降,已造成局部地区地下水径流场发生改变;水位下降导致河渠及泉水排泄地下水的形式消失;目前地下水位降落漏斗仍在扩大,郇封漏斗与温孟漏斗有相互连通而成为一个大复漏斗的趋势;煤矿开采致使地下水水质污染有向“深度”扩展的趋势;矿区排水造成疏干区扩大会进一步加剧诱发地面沉陷(塌陷)问题的产生。研究结果为保障水资源的可持续利用、促进经济、社会和环境的协调发展提供了科学依据。Groundwater environmental problems will lead to the reduction of available groundwater resources and the deterioration of groundwater environment,which will have a serious impact on human life and environment.By means of data collection,hydrogeological survey,evaluation and analysis,the change characteristics of groundwater hydrogeological conditions in the study area and the hydrogeological characteristics of the mining area were identified,and various factors affecting the groundwater environment were analyzed.The research show that the decrease of groundwater level caused by coal mining has caused the change of groundwater runoff field in some areas.The drop in water level leads to the disappearance of the form of groundwater discharged by canals and springs.At present,the groundwater level dropping funnel is still expanding,and the Huanfeng funnel and Wenmeng funnel are connected to each other and become a large compound funnel.Coal mining causes groundwater pollution to expand to"depth".Mine drainage caused by the expansion of the drainage area will further aggravate the problem of induced ground subsidence(collapse).The research results provide scientific basis for ensuring the sustainable use of water resources and promoting the coordinated development of economy,society and environment.
