摘要
以西北某区域废弃硫铁矿区为研究对象,以矿区的污染源、迁移途径、污染受体等现状调查结果为基础,分析其环境风险影响因素及特征,构建了废弃矿硐、废石堆、废弃矿区的评价指标体系;采用层次分析法对废弃矿硐、废石堆和废弃矿区的环境风险进行了定量评估;根据划分的环境风险等级,评估识别出研究区19个高风险矿硐、18个高风险废石堆和7处高风险矿区,并制定了优先管控清单,按高、中风险废弃矿硐、废石堆、废弃矿区优先治理时序,提出了“一矿一策”、“一堆一策”、“一硐一策”治理策略。
Taking an abandoned pyrite mine in a certain area in the northwest as the research object,based on the survey results of the current situation of pollution sources,migration routes,and pollution receptors in the mining area,its environmental risk factors and characteristics,and constructs the evaluation index system of abandoned mine caves,waste rock heaps,and abandoned mining areas were analyzed in this paper.The environmental risk of abandoned mine cave,waste rock heap and abandoned mining area was quantitatively assessed by using the Analytic Hierarchy Process.According to the classification of environmental risk,19 high-risk mines,18 high-risk waste rock heaps and 7 high-risk mining areas in the study area were identified in the assessment,and a priority control list was developed.According to the priority treatment sequence of high-risk and medium-risk abandoned mines,waste rock heaps and abandoned mining areas,the treatment strategies of“one mine one policy”,“one pile one policy”and“one cave one policy”were proposed.
