摘　　要：中国的煤矿行业开采进入深部以后,围岩的失稳、高地应力等因素导致围岩变形破坏严重,支护面临严峻挑战。以老石旦煤矿深部巷道支护对策项目为基础,采用理论分析、现场检测手段对内蒙古某煤矿软岩巷道进行研究,并分析软岩的变形特征,为内蒙古某煤矿的安全生产以及支护理论的研究奠定基础。After the coal mining enters deep underground in China, the instability of roadway rock, and the ex- istence of high ground stress and many factors led to the rock＇s softness, deformation and serious damage, roadway support issues faces severe challenges. In this paper, the mechanical characteristics of the surrounding rock in the soft rock roadway of an Inner Mongolia coal mine is studied by means of theoretical analysis, field measurement and laboratory study. The deformation and failure characteristics of the weak surrounding rock are analyzed. All of these will lay a foundation for the research of safety production and supporting theory for the coal mine.
