Reanalysis of spring water and its pollution causes of the Niangziguan spring in Shanxi

摘要: 山西娘子关泉水是我国北方最大的岩溶泉水之一,也是世界著名大泉,上世纪80年代前多年平均天然流量12.6 m3/s。文章利用1∶5万娘子关泉域岩溶水文地质环境地质调查项目勘探调查成果,对以下2个问题开展再分析:(1)娘子关泉水的成因,勘探等资料表明绵河南岸五龙泉、苇泽关等泉组主要接收下部中、上寒武统含水岩组岩溶水的补给,而非前人研究来源于上部中奥陶至下奥陶含水岩组补给;(2)结合水文地质条件,采用同位素等方法分析,认为部分地区煤矿老窑水的出流是导致娘子关泉水近年来加速污染的主要原因。Abstract: As one of the largest karst spring in North China, the Niangziguan spring in Shanxi well known one in the world, with an average annual natural flux of 12.6 m3/s. This work was based on the 1∶50,000 project of hydrogeology and environmental geology investigation to this spring and adjacent areas. The purpose was to reanalyze the two issues,(1) The genesis of the Niangziguan spring water;(2) The causes of its pollution. Exploration data show that the Wulong and Weizeguan springs, located at the south bank of the Mianhe river, mainly receive the recharge of karst water from the middle and upper Cambrian water-bearing formation rather than the recharge karst water from the upper middle Ordovician to lower Ordovician aquifers as suggested by previous studies. In combination with hydrogeological conditions, analysis of isotopes considers that part of the coal mine gob water flow is the primary cause for accelerating pollution of the spring in recent years.
