摘要(Abstract)：

蒲白矿产资源集中开采区分布于渭北黑腰带地区的蒲城和白水县,煤炭、石灰岩、铝土矿和粘土等多种矿产的持续开发,产生了各类的矿山地质环境问题,其中煤矿采空区塌陷及裂缝最为突出。选取了地形相对高差、岩土体特征、开采方式、有效深厚比、采空区面积比、矿山地质灾害发育密度、地下水位、压占破坏土地资源等11个指标作为评价因子,构建了矿山地质环境影响评价指标体系。采用模糊综合评判法对研究区矿山地质环境影响进行评价,并结合GIS空间分析技术划分为矿山地质环境影响严重区12个,较严重区4个,较轻区2个。评价结果与实际调查情况较为相近,较客观的反映了采矿活动对矿山地质环境的影响,并结合区内实际提出了矿山地质环境恢复治理措施建议,为矿山地质环境保护与恢复治理提供了依据。
