重庆市矿山地质环境评价方法探讨

通过对重庆市不同类型矿山地质环境调查研究,构建了包括矿山地质背景、开采状况、地质环境、自然经济环境等因素的评价指标体系。合理地划分了评价单元并确定了评价指标量化标准,通过不同隶属度函数得到相应的隶属度矩阵,利用专家评判法和频数统计法确定评价指标的权重。在兼顾矿区边界完整性的基础上,通过对各评价单元的评判、综合,得出了重庆市矿山地质环境评价分区图。为重庆市的矿山地质环境保护与恢复治理规划提供了有益的参考和借鉴,并为矿山地质环境评价和研究奠定了理论基础。

Study on the Assessment Methods for Mine Geological Environment in Chongqing City

Through the analyses of the different types of mine geological environments in Chongqing City,we set up an assessment index system including the mine geological background,mining status,geological environment problems and natural economic environment,etc.,and rationally classified the assessment units and determined the quantitative standards for assessment indices.The corresponding matrixes of membership degrees are gotten through different membership functions and weight scales of assessment indices are determined by expert judgment method and statistical method of frequency.The graph of mine geological environment assessment for different districts in Chongqing City is obtained based on minefield border through the assessment and overlapping of each assessment unit.The research provides beneficial use and references for the mine geological environment protection and treatment planning in governments of Chongqing City at all levels and also provided a theoretical foundation for further study and mine geological environment assessment.
