废弃矿井水资源化利用现状及展望

Current status and prospects of water resources utilization in abandoned mines

随着我国关闭及废弃煤矿数量的增加,其产生的矿井水也被大量排出、废弃,不仅导致了可再利用水资源的大量浪费,而且还威胁着矿区生态环境。综合分析了国内外矿井水资源化利用现状以及废弃矿井水资源化利用途径,并选用STIRPAT模型对我国未来废弃矿井水的供需关系进行了预测,在此基础上,针对供需关系对我国未来废弃矿井水进行了平衡分析。最后,对我国废弃矿井水资源化及其他非常规水资源的利用提出了措施与建议。

With the increase of the number of closed and abandoned coal mines in China,the mine water produced by it has been discharged and discarded in large quantities,which not only leads to a large waste of reusable water resources,but also threatens the ecological environment of the mining area. This paper comprehensively analyzed the current situation of water resources utilization in mines at home and abroad and the ways of utilizing water resources in abandoned mines. The STIRPAT model was used to predict the supply and demand relationship of abandoned mine water in China. And a balance analysis was conducted on the supply-demand relationship of waste mine water in the future. Finally,measures and suggestions for the utilization of water resources in abandoned mines and other unconventional water resources in China were proposed.
