源于煤矸石充填体的地下水污染风险评价

Risk Assessment of Groundwater Pollution from Coal Gangue Filling Body

为了解决煤矸石充填体对地下水的污染问题,在理论研究了地下水污染风险的前提下,提出了煤矸石充填区地下水污染风险的定义。并且基于迭置指数法从煤矸石充填体、地下水固有脆弱性以及地下水价值功能3个方面建立了煤矸石充填体对该区域地下水污染风险的指标体系及综合风险指数模型,对其风险等级进行划分,为煤矸石充填塌陷区域的地下水保护及污染的防控与地下水应用开发提供更为可靠的指导意义。

In order to solve the problem of groundwater pollution caused by coal gangue backfills, under the premise of a theoretical study of groundwater pollution risk, the definition of groundwater pollution risk in coal gangue filling area was proposed. Based on the superposition index method, an indicator system for the risk of groundwater contamination and a comprehensive risk index model for coal gangue fillings from the coal gangue backfill, groundwater inherent vulnerability and groundwater value functions were established to classify the risk levels. It would provide more reliable guidance for groundwater protection and pollution prevention and control and groundwater application and development in coal gangue filling subsidence areas.
