为了减弱地质灾害对矿井开采的影响，本文以杜儿坪矿为研究对象，对杜儿坪矿区所在地地质灾害的类型进行分析，给出了崩塌、滑坡、不稳定斜坡及泥石流等灾害的发生机理，同时研究发现随着开采厚度的增加，地表下沉量增大，开采深度越大，地表下沉量越小。通过分析地质灾害发生机理给出了斜坡及采空区下沉地质灾害的防治措施，为矿区安全开采做出一定的贡献。“,”in order to weaken the influence of geological disasters on mine mining, this paper takes Duerping mine as the research object, analyzes the types of geological disasters in Duerping mine area, and gives the occurrence mechanism of collapse, landslide, unstable slope and debris flow. At the same time, it is found that with the increase of mining thickness, the surface subsidence increases, and the mining depth increases, The smaller the surface subsidence is. Through the analysis of the mechanism of geological disasters, the prevention and control measures of slope and goaf subsidence geological disasters are given, which makes a certain contribution to the safe mining of the mining area.
