Progressive failure behavior and stress evolution characteristics of fractured coal-rock combination structure

Progressive failure behavior and stress evolution characteristics of fractured coal-rock combination structure

The structural weak planes have a significant impact on the mechanical properties of rock (coal) masses. Under the influence of geological structures or mining activities, the surrounding rock in deep mines commonly exhibits a coal-rock combination structure containing macroscopic fractures. Therefo...
