贵州省矿区岩溶区广布、水文地质条件复杂，同一矿区内常存在多个水文地质单元，其水文地质条件与其他占国内大多数的北方矿区差异较大。鉴于贵州省矿区的独特性，本文以织纳矿区织金区为例，通过分析矿区规划特点及地下水环境特点，提出贵州省矿区地下水环境影响评价特点及采用预测方法时需重点考虑的因素，比如计算导水裂隙带高度、影响半径、受影响水资源量时，尽量选取多个典型矿井进行评价；居民饮用水源泉点受影响情况逐个分析等。%In Guizhou Province,karst area was widespread and hydrogeological conditions were com-plex in mining areas. Usually there were more than 1 hydrogeological units in a mining area,which was very different to those in north China. In view of the uniqueness of Guizhou Province mining are-as,this thesis reviewed the mining area planning and analyzed characteristics of groundwater environ-ment in Zhijin Mining Area ,and then put forward comments for groundwater environmental impact assessment and predicting methods for Guizhou Province mining areas. For example,when we calcu-lated the height of water flowing fractured zone,influenced radius of groundwater and influenced wa-ter volume,plenty of typical mines should be included. When drinking water source was involved, each drinking spring should be analyzed.
