河南省煤矿矿井水资源综合利用研究

Study on comprehensive utilization of mine water resources in coal mines of Henan Province

煤矿矿区长期大量疏排地下水不仅造成区域地下水资源被浪费,加剧了水资源短缺的矛盾,同时排至地表的矿井水也成为土壤、地表水、地下水及生态环境的污染源。研究了矿井水资源化利用情况和利用问题,分析了矿井水资源化利用途径以及矿井水的处理工艺,针对焦作矿区、鹤壁矿区、平顶山矿区、新密矿区、永城矿区等矿区,提出了切实可行的提高各矿区矿井水利用水平途径的措施,主要利用方向为向电厂供水、农业灌溉用水、工业用水、生态用水等。研究可减少因煤矿开采对水资源的浪费,从而为河南省缺水矿区工农业生产提供水资源保证。

The long-term large-scale drainage of groundwater in coal mining areas not only leads to the waste of regional groundwater resources,but also exacerbates the contradiction of water resource shortage.At the same time,the mine water discharged to the surface also becomes a pollution source of soil,surface water,groundwater,and ecological environment.The paper studies the situation and utilization of mine water resources.Based on this,it analyzes the ways of mine water resources utilization and the treatment process of mine water.For Jiaozuo mining area,Hebi mining area,Pingdingshan mining area,Xinmi mining area,Yongcheng mining area and other mining areas,it puts forward practical measures to improve the level of mine water use in each mining area.The main use directions are to supply water to power plants,agricultural irrigation water,industrial water,ecological water use,etc.Research to reduce the waste of water resources due to coal mining,and provide water resources guarantee for industrial and agricultural production in the water shortage mining area of Henan Province.
