大型缺水矿区水资源开发利用研究

Study on Water Resources Development and Utilization in Water Shortage Large Coal Mining Area

为缓解神东矿区水资源短缺的现状,在全面分析区内水资源条件的基础上,采用充水系数法计算出该区采空区积水资源量为3 930.7万m3。同时分析了矿区洁净水工程供水潜力有限,而工业复用水工程的供水和矿井水开发利用潜力较大,矿区内部水资源开发利用潜力为1.5万m3/d,外部水资源可做为远期储备。进而给出了适合神东矿区现在和未来的水资源开发利用模式,以及枯水年水资源开发利用建议,从而达到神东矿区水资源综合利用,缓解水资源供需矛盾的目的。

In order to relax the present status of the water resource shortage in the Shendong Mining Area,based on the full analysis on the water resources conditions in the mining area,the water accumulated resources value in the goaf of the mining area was about 39.307 million m3 calculated with the water filling coefficient method.Meanwhile the paper analyzed that the water supply potential of the clean water projects in the mining area would be limited,but the water supply potential of the industrial recycle water project and the mine water development and utilization potential would be high.The development and utilization potential of the water resources in the mining area would be 15 000 m3/day and the water resources beyond the mining area could be for the long term reserves.Therefore the water resources development and utilization mode suitable for the present and future Shendong Mining Area was provided and the water resources development and utilization proposals of the low flow year were provided.Thus the target of the water resources comprehensive utilization and the water resources supply and demand contradiction relaxed was reached in Shendong Mining Area.
