Abstract
Based on a regional hydrogeological survey,the hydrogeochemical characteristics of a karst groundwater system in the Xinggong coal field were analyzed in this paper.The results show that from recharge zones to discharge zones,the hydrochemical type of groundwater changes from HCO3-Ca(Mg) to HCO3.SO4-Ca(Mg) or SO4.HCO3-Ca(Mg) type,TDS and the ratio of Sr2 + to Ca2 + in groundwater increase.Isotopic characteristics indicate that groundwater is mainly recharged from modern precipitation.The recharg.
