摘要
铜陵作为典型的矿业型城市,依托于矿产资源开发,多年来采矿活动也产生了各种类型的矿山地质环境问题。为确定铜陵市矿山地质环境影响状况并划定影响程度分区,通过整理铜陵地区“矿山地质环境调查报告”“、矿山地质环境保护与土地复垦方案”,确定矿山地质环境问题类型、分布特征及其形成原因。根据指标选取原则确定评价指标,按照指标属性采用定量和定性方法将指标标准化,并构建评价指标体系,最终使用AHP层次分析+模糊数学综合评判,将铜陵市矿山地质环境影响状况分为严重区、较严重区、一般区3个等级。结果表明:矿山地质环境影响严重区(Ⅰ)8个、较严重区(Ⅱ)6个、一般区(Ⅲ)4个;矿山地质环境影响程度严重区主要围绕在铜陵主要矿集区及矿产地周边,分区结果与矿山地质环境实际情况基本吻合,可作为当地政府划定矿山地质环境保护与治理分区的基础依据。
As a typical mining city,Tongling relies on the exploitation of mineral resources.Over the years,mining activities have been accompanied by various types of mine geological environment problems.In order to determine the impact status of the mine geological environment in Tongling and delimit the zon⁃ing of the impact degree,the article determines the types,distribution characteristics and causes of the mine geological environment problems by sorting out the“mine geological environment survey report”and“mine geological environment protection and land reclamation plan”in Tongling.The evaluation index was deter⁃mined according to the selection principle of the index,the index was standardized by quantitative and qual⁃itative methods according to the index attributes,and the evaluation index system was constructed.Finally,the AHP hierarchical analysis and fuzzy mathematics comprehensive evaluation were used to classify the geological environment impact of mines in Tongling City into three levels:serious area,serious area and gen⁃eral area.The results show that there are 8 serious(Ⅰ),6 serious(Ⅱ)and 4 general(Ⅲ)areas affected by mine geological environment.The areas with serious impact degree of mine geological environment are main⁃ly centered around the main mining conce,ntration area and the surrounding area of the mining area.The zoning results are basically consistent with the actual situation of mine geological environment,which can be used as the basis for the local government to delimit the zoning of mine geological environment protection and treatment.
