Study on Deformation and Strength Characteristics of Hollow Cylindrical Rock Under Complex Loading Conditions

Drilling a borehole and inserting high-pressure fluid to induce rock fracture is a rock-mass pre-conditioning method in block caving mining of hard rock metal mines, and the borehole surrounding rock is under the complex loading conditions with in-situ stress and borehole inner pressure. In order to...
