Damage evolution characteristics of coal body in borehole at deep roadway wall and strength weakening mechanism of surrounding rock in borehole

Damage evolution characteristics of coal body in borehole at deep roadway wall and strength weakening mechanism of surrounding rock in borehole

Coal seam drilling pressure relief technology is an important means to prevent and control rock burst disasters. Using the self-developed real-time CT scanning true triaxial loading test system, the force-strain law and internal crack propagation evolution characteristics of two different stress typ...
