High Temperature Rock Laboratory

The laboratory is equipped with a high temperature rock true-triaxial testing apparatus ,which can perform hydraulic fracturing experiment on rock blocks with size up to 300mm x 300mmx300mm at confining pressures up to ~100 MPa and temperatures up to 400 ℃ while simultaneously recording and locating acoustic emission signal. We have completed preliminary study on the fracture failure of granite and further experimental research will be carried out on hydraulic fracturing of granite under thermal shock and temporary plugging fracturing.
