Abstract: Understanding the failure process in frozen porous rock is of great importance to both geomorphology research and engineering design in cold regions. The mechanical behavior of frozen porous rock has its own particularity ...

Abstract: Coal mine shaft excavation with the freezing method causes surrounding rock deformation under lateral unloading. In this paper, the failure process of frozen sandstone under lateral unloading was studied based on the ...

Abstract: To study the energy characteristics and damage laws of frozen rock during mine freezing, a triaxial compression test and synchronous acoustic emission test of frozen sandstone are conducted. The results show that (1) the ...
