摘　　要：煤企生产过程中产生的废水是造成地下水污染的主要因素。通过环境水文地质调查,对盘关向斜区域煤企生产活动造成地下水污染的主要方式进行分析,查明区内主要污染源—煤矿污水、洗煤水及堆场淋滤水通过地表水体、溶隙、落水洞等途径进入岩溶含水层污染地下水,又经岩溶管道长途运移排泄至地表,造成暗河出口地表河流污染的污染模式。其污染的三种基本模式为地表水体污染、包气带污染以及地下水污染。针对煤区岩溶地下水污染表现的滞后性和周期性,提出煤区岩溶地下水污染防治对策,对区内环境保护工作具有一定参考价值。The waste water produced in the process of coal production is the main factor causing groundwater pollution.Through the environmental hydrogeology survey,analyses the main cause of groundwater pollution in the Panguan Syncline area of coal enterprise production activities,find out the main pollution source of coal mine sewage,coal washing water and yard leaching water and by surface water leaching water,karst sinkholes and other ways to enter the karst aquifer of groundwater pollution,but also by the long-distance migration of karst conduit the excretion of pollution to the surface,caused the pollution of the underground river outlet surface. The three basic modes of pollution are surface water pollution,vadose zone pollution and groundwater pollution. In view of the hysteresis and periodicity of karst groundwater pollution in coal area,the countermeasures for prevention and control of karst groundwater pollution in coal area are put forward,which has certain reference value for environmental protection work in the district.
