摘要
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 recharge elevation calculated with isotopes and the flowing system divided by hydrogeological surveys are coincide with the conclusions drawn from water chemistry analysis for the karst groundwater.oft-com:office:office" />
