摘　　要：新疆伊犁地区的矿山地质灾害的发生已经严重影响了当地的经济发展,并威胁着人们的生命和财产安全。为了减少矿山地质灾害发生的频率,必须建立有效的预警和保护机制。最重要的首要任务之一是详细分析矿山地质灾害的形成机理。通过对新疆伊犁地区矿山地质灾害易发区的基本地质环境条件、地质灾害发生的基本特征、形成因素的研究,选择了具有代表性的区域作为研究对象,详细分析了地质灾害的形成机制,破坏模式可以解释为山体后缘张裂,局部蠕动变形、滑移,整体剪出三个阶段,简单概括为:张裂—蠕变滑移—剪出破坏模式,形成机制属于蠕滑-拉裂型。The occurrence of mine geological disasters in Yili area of Xinjiang has seriously affected the local economic development and threatened people's life and property safety.In order to reduce the frequency of mine geological disasters,it is necessary to establish an effective early warning and protection mechanism.One of the most important tasks is to analyze the formation mechanism of mine geological disasters in detail.Based on the study of the basic geological environment conditions,the basic characteristics and the formation factors of the mine geological disaster prone areas in Yili area,Xinjiang,the representative regions are selected as the research objects,and the formation mechanism of geological disasters is analyzed in detail.The failure mode can be interpreted as the following three stages:tensile fracture of mountain rear edge,local creep deformation,sliding and overall shear out,It can be simply summarized as:tensile crack creep slip shear out failure mode,and the formation mechanism belongs to creep tensile crack type.
