【摘要】 本文通过阜新矿区500 km2的地下水体污染状况的调查，得出矸石山是该区地下水污染的主要污染源之一。并以新邱南矸石山为实例，建立了地下水流动数学模型、污染物运移数学模型，通过SOM法进行数值求解，预测了污染物浓度的时空分布特征；对污染晕的大小、分布范围进行了可视化模拟。利用模糊数学综合评判理论，对新邱南矸石山于家沟一带进行了水质评价，并与传统的内梅罗法进行了比较；论述了目前应用神经网络中BP网在评价地下水质中经常存在的问题。针对该矿区实际，作者在化废为宝、消除矸石山方面；防止矸石山淋滤液对地下水污染的措施方面；污染含水层治理等三个方面论述了减弱灾害的方法。更多还原

【Abstract】 The waste rock hill is one of the main contamination sources that cause the pollution of groundwater by investigating groundwater pollution conditions of Fuxin coal mining areas whose area is about 500km2.In this paper, taking the waste rock hill in Xinqiu as an example, the numerical model of groundwater flow and contaminant migration are established. The coupled model is numerically solved by SOM method, which predict the temporal and spatial distribution features of contaminant concentration. Additionally, the visualization of the pollution halo areas and distribution range are presented.The fuzzy mathematical colligate evaluation theory is adopted to evaluate the groundwater quality in Yujiagou area and it is compared with the Nemero index method. The exiting problems of the BP method in water quality assessment are discussed.In light of the real mining area conditions, the methods to weaken the disasters are presented on waste rock hill utilities, preventing the leachate pollution and controlling the polluted aquifer.更多还原
