摘　　要：突水是矿山深部开采面临的主要挑战之一,对于水下开采矿山,分析研究影响矿山突水的关键因素是防治突水事故发生的重要环节。在分析矿山工程地质条件对矿山突水的影响的基础上,进一步分析上覆岩层的渗透性能及断层破碎带对渗透性能的影响,通过构建改进伯格斯本构模型,分析研究岩石的蠕变断裂特点,为采取相关措施避免矿山突水事故发生提供理论支撑。在对含有断层和裂隙的围岩的力学性能和破坏过程的分析中,得到矿山突水事故发生评价的重要影响参数,为下一步矿山突水事故的预防和相关措施的实施提供了理论参考和工作指导。Mine water inrush is one of the main challenges in deep mining.The analysis and study of the key factors affecting mine water inrush is an important part of prevention and control of water inrush accidents for underwater mining.Based on the analysis of the influence of mining engineering geological conditions on mine water inrush,the permeability of overlying strata and the influence of fault fracture zone on permeability were further analyzed.By constructing a modified Burgers constitutive model,the creep fracture characteristics of rocks were analyzed,which provided a theoretical support for taking relevant measures to prevent mine water inrush accidents.In the analysis of the mechanical properties and failure process of the surrounding rock with faults and fractures,the important influencing parameters of mine water inrush accident were obtained.It provided a theoretical reference and work guidance for the prevention of mine water inrush accident and related measures.
