【摘要】：针对制约我国煤炭开发战略西移面临的水资源短缺问题,避免矿井水外排地表蒸发损失和造成土壤盐碱化,开辟节省土地资源和节约建设运行费用的矿井水储用的新途径,保护和利用西部矿区宝贵的矿井水资源,提出了矿井水井下储存利用的新理念,即利用煤炭开采形成的采空区作为储水空间,用人工坝体将不连续的煤柱坝体连接构成复合坝体,建设煤矿地下水库。开发了水库水量预测、水库选址、库容计算、坝体建设、安全运行和水质保障等关键技术,建立了煤矿地下水库技术体系,在神东矿区建设了示范工程。目前已建成32座煤矿地下水库,储水量达3100万m3,供应了矿区用水量的95%以上,为矿区发展提供水资源保障,为我国煤炭开采水资源保护利用提供了新的技术途径。
[Abstract]:In view of the shortage of water resources which restricts the westward migration of coal development strategy in China, it is necessary to avoid the loss of evaporation and salinization of soil, and to open up a new way to save land resources and save the cost of construction and operation of mine water storage. Based on the protection and utilization of valuable mine water resources in western mining area, a new concept of storage and utilization under mine wells is put forward, that is, the goaf formed by coal mining is used as water storage space. The composite dam body is constructed by connecting the discontinuous coal pillar dam body with artificial dam body, and the underground reservoir in coal mine is constructed. The key technologies such as reservoir water volume prediction, reservoir location selection, reservoir capacity calculation, dam construction, safe operation and water quality guarantee are developed. The underground reservoir technology system of coal mine is established and a demonstration project is built in Shendong mining area. At present, 32 underground reservoirs in coal mines have been built with a storage capacity of 31 million m3, supplying more than 95% of the water consumption in the mining area, providing water resources for the development of mining areas and providing a new technical way for the protection and utilization of water resources in coal mining in China.
