Abstract：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.
