Experimental study on influence of lithology on directional propagation law of type-I cracks
To study the influence of lithology on the directional propagation law of rock type-I cracks, a simple crack directional propagation device was used to conduct loading tests on three rock types. The acoustic e...

Anchoring effect and energy-absorbing support mechanism of large deformation bolt
To research the anchoring effect of large deformation bolt, tensile and drawing models are established. Then, the evolution laws of drawing force, bolt axial force and interfacial shear stress are analyzed. Ad...
