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.
