为了解灰岩地下水质量现状，通过潘北煤矿－580 m水平C3Ⅰ组灰岩放水试验，采集井下14个疏放水孔地下水，运用综合污染指数法和F值法相结合对实验监测所得到的数据进行污染评价。由此得出如下结论：氯化物、溶解性总固体、铁、铬等重金属元素对矿区灰岩地下水质量影响比较大，这4项评价因子占总评价因子污染分担率的83％；矿井－580 m放水大巷东翼水质整体好于西翼；井下部分疏放水孔地下水水质较差，可能已经受到来自煤矿开采及浅层地下水的污染。

In order to find out the quality status of limestone underwater , through dewatering test of group C 3Ⅰlimestone in Panbei coal mine 580 meters underground , groundwater from 14 water-draining holes under-ground was collected.With the combination of synthetical pollution index method and F value method ,the data obtained from the experiment monitoring was evaluated.Conclusions are as follows:firstly, chloride, total dis-solved solids and heavy medals like iron , chromium, etc, these four factors accounting for 83%of total pollu-tion share rate , have greatly affected the quality of limestone groundwater in mining area; secondly , water quality of east wing turns out to be better than that of west wing in water -release tunnel 580 meters under-ground;thirdly , groundwater in part water-draining holes is of inferior quality and has already got contamina-ted by shallow groundwater and coal mining.
