针对淮北采煤沉陷区水资源综合利用问题,研究了该区水资源补给与储蓄条件,总结分析了该区平原水库建设的可行性。结果表明,该矿区因多煤层开采,且累计开采厚度大,从而造成地表大面积大幅度沉陷。加之该区良好的地貌与第四系水文地质条件,沉陷盆地可为雨洪资源提供良好的蓄水空间。此外,由于矿区内较高的浅层地下水水位和较大的开采沉陷幅度,枯水季节浅层地下水会越流补给沉陷区,因此沉陷区内形成常年稳定的积水区。矿区的雨洪资源、浅层地下水和相邻区域天然水系的整合可成为库区稳定的补给源。有利的水文条件和环境保护措施可以使库区水质得到有效控制,良好的平原水库建设条件使该区水资源得到有效保护利用,大幅促进了地区经济发展。

According to the problem of comprehensive utilization of water resources in Huaibei mining subsidence area. The paper studied the water supply and savin g condition in the area and analyzed the plain reservoir construction feasibility in this area.Results showed this area was coal seam mining and accumulated large mining t hickness,thus causing significant surface subsidence.Meanwhile,the good landscape,quaternary hydrogeological conditions and subsidence basin could provid favourable water storage space for rain and flood resources.What's more,due to the higher shallow groundwater level and larger mining subsidence ,shallow groundwater resources in dry season would flow to supply the subsidence area. Thus,the subsidence area formed stable water zone. The rain and flood resources,shallow groundwater and the integ ration of adjacent natural water system could be the stable reservoir supply source.Favorable hydrological condition and proper environmental protection measures could e ffectively control the reservoir water quality.Good construction conditions of plain reservoir made the water resources obtain effective protection and utilization and greatly promoted the regional economic development.
