山东陶枣煤田矿业开发对裂隙岩溶水的污染机理及防治对策

The mechanism and prevention measures of fracture-karst water pollution induced by mining at Taozao coalfield in Shandong province

陶枣煤田周边分布有丰富的裂隙岩溶水资源,且易于开采,为区内城市生活的主要供水水源。长期以来,受煤炭资源开采影响,岩溶地下水受到了不同程度的污染,供水水质难以保证。本文在对裂隙岩溶地下水水质进行污染评价的基础上,根据污染时空分布特征以及地质、构造条件,分析了区内岩溶地下水的污染机理,并提出了可行的防治措施。

Taozao coalfield has abundant fracture-karst water resource characterized by easy exploiting and is the major water supply source for the cities. For a long time,the quality of the karst groundwater shows varying degrees of pollution with the mining of the coal resource. So,it is difficult to guarantee the good quality of supply water. Based on the pollution assessment of the water quality,this paper analyzes the pollution mechanism of the fracture-karst water and put forwards the achievable counter measurements according to the characteristics of time-space distribution of pollution,geology setting and structural environment.
