Analysis of Energy Transmission and Deformation Characteristics of Coal-Rock Combined Bodies

Wang Tuo et al.

Summary: This study investigated the energy interchange law and interaction relationship between coal and rock in a coal-rock combined body through loading tests. The experimental results revealed that the surrounding rock pressure affects the strain growth rate and energy density of rock, and the energy accumulation increases with the increase of coal proportion.

Influence of Confining Pressure Unloading Rate on the Strength Characteristics and Fracture Process of Granite Using Lab Tests

Jiaqi Guo et al.

Summary: The study investigated the mechanical behaviors and fracture process properties of granite under different combinations of initial confining pressures and unloading rates. It was found that the specimens exhibit characteristics of ductility at small unloading rates and brittleness at large unloading rates. The cohesion of granite specimens decreases with increasing unloading rate, while the internal friction angle increases.
