根据地质构造、地形地貌、地层结构与埋藏特征及补径排条件等条件，划分了河南省主要煤矿区的岩溶水系统。对地下水的补径排及水化学特征进行了分类，分析了不同岩溶地下水水系统特征对矿区水害的影响。研究结果可为河南省煤矿开采中存在的水害隐患及其防治提供科学依据。%Based on geologic structure, landform, strata structure, characteristics of burying and precondition of recharge-runoff-discharge system, karstic groundwater systems in coal mine areas of Henan province are classified. Moreover, the recharge-runoff-discharge types and hydrochemical characteristics are also be analyzed and classified. The influence of tu-nique properties of various groundwater systems on hydrogeological disasters is studied in this paper.
