| Abstract: |
| After the coal mining into the deep in China, the instability of roadway rock, and the existence of high ground stress and many factors led to the rock’s softness, deformation and serious damage, roadway support problems faces severe challenges. In this paper, the mechanical characteristics of the surrounding rock in the soft rock roadway of the Neimenggu coal mine is studied by means of theoretical analysis, field measurement,laboratory study. And 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 of Neimengu coal mine. |
