开采区矿山地质环境综合分级定量评价方法

以实现评价矿山地质环境为目的，提出开采区矿山地质环境综合分级定量评价方法。以非金属矿山为研究对象，针对其周边地质环境和生态环境，建立开采区矿山地质环境综合分级定量评价指标体系。采用模糊层次分析算法，对该指标体系内的一级指标和二级指标实施相对重要程度赋值计算后，通过GIS空间分析算法，分析开采区矿山地质环境综合等级赋值频率分布情况，确定矿山地质环境评价的分区阈值，得到开采区矿山地质环境综合分级定量分区结果。实验结果表明，该方法可有效评价非金属开采矿区地裂缝、含水层破坏、地形地貌景观破坏等二级指标等级，可依据二级指标评价结果评价其一级指标等级，具备较好的应用性。

Comprehensive classification and quantitative evaluation method of mine geological environment in mining area

In order to realize the evaluation of mine geological environment,a comprehensive classification and quantitative evaluation method of mine geological environment in mining area is proposed.Taking non-metallic mines as the research object,aiming at its surrounding geological environment and ecological environment,a comprehensive classification and quantitative evaluation index system of mine geological environment in mining areas is established.After calculating the relative importance of the primary and secondary indicators in the index system by using the fuzzy analytic hierarchy process,the frequency distribution of the comprehensive grade assignment of the mine geological environment in the mining area is analyzed through the GIS spatial analysis algorithm,the zoning threshold of the mine geological environment assessment is determined,and the comprehensive grading and quantitative zoning results of the mine geological environment in the mining area are obtained.The experimental results show that this method can effectively evaluate the secondary index grades of ground fissures,aquifer damage,landform and landscape damage in non-metallic mining areas,and can evaluate the primary index grades according to the secondary index evaluation results,which has good applicability.
