大同市矿山地质环境风险评价

摘要

In view of the interaction between effects of mine exploitation and geological environment fragility,this paper puts forward the definition and methods of risk evaluation for mining geological environment.According to the feature of local mining geological environment in Datong,the evaluation object is divided into high risk areas,medium risk areas and low risk areas,through developing an assessment method of an indicator system (AMIS),which is based on the impact of mine exploitation and the fragility of geological environment,and employing the analytic hierarchy process (AHP) to obtain the index weight coefficients.Comparison of the calculation of mathematical models and the fuzzy comprehensive assessment is performed.Advice on risk prevention and control is proposed based on the research results.%文章从矿业开发影响和地质环境脆弱性相互作用的角度出发,提出了矿山地质环境风险评价的定义及方法.将大同市作为评价对象,建立了矿业开发影响力和地质环境脆弱性评价指标体系,利用层次分析法进行指标权重分析,进而通过模糊综合评判数学模型进行计算和对比;最终将大同市划分为矿山地质环境高风险区、中风险区和低风险区.并根据评价分区结果,提出了风险防控建议.
