| 摘 要： | 矿产资源开发带来了许多环境问题,对矿山地质环境质量进行评价对矿山的未来发展和资源可持续利用十分必要。笔者选取环境污染、地质灾害和资源利用等3个评价指标作为一级变量层,构建了大气污染、土壤污染、水污染及矿渣占地等影响矿山地质环境的11个二级评价因子,建立了抚顺东露天矿地质环境评价体系。运用层次分析法建立了11个二级评价因子两两对比的判断矩阵,根据矩阵特征向量值的大小确定评价因子权重,并通过一致性检验验证权重是否合理。根据矿区的现状、辽宁省内环境指标平均值及相关国家标准,将矿山环境分为优、良、中、差4个等级,建立抚顺东露天矿地质环境评价体系模型。评价结果表明:抚顺东露天矿优秀区域约6.2×106m2,占总面积的67%;环境良好区约2.86×105m2,占总面积的3%;环境中等区约2.713×106m2,占总面积的30%;总体上矿山地质环境较好。

| Abstract: | The exploitation of mineral resources has brought many environmental problems.It is necessary to take the geological environment evaluation for the mine＇s future development and sustainable use of resources.The authors select three evaluation indexes,including environmental pollution,geological disaster and use of resources,as the first variable layer; and construct 11 evaluation factors including air pollution,soil pollution,water pollution,slag covering and others,as the evaluation indexes on the second variable layer,to establish the geological environment evaluation system for the East Strip Coal Mine of Fushun.On the basis of analytic hierarchy process,pairwise comparison judgment matrix has been established,including 11 evaluation factors,which weights are determined according to the eigenvectors of the judgment matrix and are verified by consistency check.The mine environments in the East Strip coal mine are divided into 4 levels of excellent,good,medium and poor according to present status of the mine,average environment indexes in Liaoning,and national standards,and the geological environment evaluation system model for the mine is established.The evaluation results indicate that the excellent area of the mine is 6.2 × 106m2,being 67％ of the total area; good area is 2.86 × 105m2,being 3％ of the total area;moderate area is 2.713 × 106m2,being 30％ of the total area.Overall the environment of the East Strip coal mine is good. |
