摘　　要：为了消除屯兰矿崩塌、崩积物地质灾害,研究了屯兰矿地质灾害稳定性,研究区B1、B2两处崩塌均属黄土、滑移式崩塌,规模等级属小型,处于欠稳定状态,危害程度中等,地质灾害发育程度强,危险性大。参照相关规定对地质灾害防治等级的划分标准,防治工程级别为二级。基于此,根据崩塌发育地形地貌、斜坡形态特征、形成机理以及灾情现状等情况,提出了治理措施,采取后缘削方分级、坡面防护、外围截排水、坡面绿化等措施进行综合治理。研究为后期地质灾害治理提供了技术支持。In order to eliminate the geological disasters of collapse and colluvium deposits in Tunlan Mine,this paper studies the stability of geological disasters in Tunlan Mine.The two collapses in the study area B1 and B2 are both loess and sliding collapses,with small scale and in an unstable state,the degree of harm is medium,the degree of development of geological disasters is strong,and the danger is high.According to the classification standards for geological disaster prevention and control levels in relevant regulations,the level of prevention and control engineering is Level 2.Based on this,according to the topography of collapse development,slope morphological characteristics,formation mechanism and the current situation of the disaster,treatment measures are put forward,and comprehensive treatment measures are taken such as trailing edge cutting and classification,slope protection,peripheral interception and drainage,and slope greening.The research provides technical supporting for the later geological disaster management.
