摘要
用环境同位素技术研究地下水的补给是当前国内外较为新颖有效的方法之一。本文对研究区93个水样的稳定同位素18O值和D值进行了分析和计算。研究结果表明:矿区的岩溶水(包括矿井水)主要是来源于山区大气降水的补给;平禹一矿岩溶水主要来自于矿区北部和西北部山区岩溶水的侧向径流,直接水源为白沙水库地区的地下水;白沙水库一带地下水主要补给来源是当地大气降水。研究结果为该矿区采取有效的防治水措施提供了科学依据。
The environmental isotopic technique is one of the new and effective ways to research the groundwater recharge at home and abroad.The paper analysed and calculated the 18O and D of 93 water samples from study area.The results showed that the recharge source to the karst water（including mine water）,in mining area is atmospheric precipitation in mountainous area,and the karsr water in 1st mine of Pingyu come from the sidewise runoff at north and northwest the direct recharge source is the groundwater at Baisha Reservior area,and the atmospheric precipitation is the main recharge source to the groundwater of Baisha reservoir area.This research results can provide scientific basis for flood control of Pingyu mining area.
