Fractal Characteristics of Coal and Sandstone Failure under Different Unloading Confining Pressure Tests
To analyze the fractal characteristics of coal rock failure under unloading conditions, triaxial unloading confining pressure tests were carried out on coal and sandstone rock samples under different unloading rates and initial confining pressures. We examined the distribution of the surface cracks...
