煤矸石充填体对地下水污染风险的评估
|
摘要
随着固体充填采煤技术的日益推广,煤矸石充填矿井对地下水环境污染日益严重。为了及时了解并掌握煤矸石充填对矿井地下水的污染风险,在对地下水污染风险理论研究的基础上,运用迭置指数法和层次分析法,构建了煤矸石充填矿井对地下水污染风险的指标体系及模型,并对其风险等级进行划分,为充填矿井的地下水保护及污染的防控与应急处理提供可靠指导。
With the increasing popularization of solid stoping-and-filling technology,the groundwater environmental pollution of coal gangue filled mine was becoming increasingly serious.In order to grasp the groundwater pollution risk of coal gangue filled mine,based on theoretical research of the groundwater pollution risk,the indicator system and model of groundwater pollution risk of coal gangue filled mine were built by adopting overlap index method and analytic hierarchy process,and its risk level was divided,which provided reliable guidance for the prevention,control and emergency treatment of groundwater pollution and protection of filling mine.
