通过现场调查,并运用数值模拟技术、室内试验以及模糊综合评价等方法,对徐州东部矿区水资源化利用进行了研究.结果表明：按平水年计算,枯水期岩溶水补给量为1 008.3m3/h,丰水期为1 425.4m3/h,随着矿井排水量增加,岩溶水补给量也增加;研究区矿井水水质总体良好,除新河煤矿矿井水水质因闭坑后受采掘巷道和采空区污染较重为Ⅴ类水质外,其他煤矿都为Ⅰ类水质.

Taking such methods as on site field investigation,numerical simulation,laboratory experiment and fuzzy comprehensive assessment,utiliazation of coal mine water in the east of Xuzhou city has been studied.Results show as follows： recharge of karst is 1 008.3 m3/h in dry season and 1 425.4 m3/h in wet period in normal flow year,and the karst recharge is increasing with the increase of mine discharge;The mine water quality is generally good,and the water quality of mines are all Grade I except that the water quality of Xinhe coal mine is Grade V,which is seriously contaminated by mining tunnel and gob after closure.
