Research on Temperature-pressure Coupling Model During Crack Evolution of Coal in Coalfield Fire Area
Abstract：To definitely investigate the uature of fracture generation and the mechanism of temperature-pressure coupling in the cracks evolution process of coal mass,we analyze the effect of temperature,pressure,temperature-pressure coupling on coal fracture in this paper;combining damage theory and fractture criterion,we buill temperature-pressure coupling model,and illustrate the coupling mechanism fiom theory and mathematical relationship.The nature of coal under temperature-pressure coupling failure can be described using the principle of first damage and then following the failure criterion.
