| 摘 要： | 在查明地质灾害孕灾背景、发育现状、矿区开采现状的基础上，基于定性结合定量的评价方法，开展了矿区地质灾害危险性评价.基于评价结果和野外调查情况，总结采矿活动对矿区主要地质灾害的影响.主要成果如下：1）总结了研究区地质灾害的发育及分布特征；2）综合分析矿区孕灾环境及地质灾害致灾因子，构建了研究区危险性评价指标体系，以ArcGIS为工作平台，以斜坡单元为最小评价单元，进行了由地质灾害易发性到地质灾害危险性的评价；3）针对评价结果，理论分析了采矿活动对滑坡、崩塌、泥石流及塌陷等灾害发生的影响方式.

| Abstract: | On the basis of ascertaining the hazard-inducing environment, development situation of geological disasters and mining status, the geohazard risk assessment in mining areas is carried out with qualitative and quantitative methods. According to the assessment results and field survey, the influence of mining activities on main geohazards are summarized. The development and distribution characteristics of geohazards are studied. The disaster-causing environment and factors are analyzed comprehensively to construct the risk assessment index system. With ArcGIS as the working platform, the assessment from the susceptibility to risk is carried out with slope unit for minimum assessment unit. Based on the assessment results, the influence modes of mining activities on landslide, collapse, debris flow and subsidence are analyzed theoretically. |
