Paper presented at the ISRM SINOROCK 2013, June 18ā€“20, 2013
Paper Number: ISRM-SINOROCK-2013-039
... Abstract Mechanical characteristics and energy properties of granite under uniaxial compression after high temperature have been researched. The results show that energy conversion during rock deformation and failure is a dynamic process, and it can be mainly divided into four subprocesses...

... produce strong acoustic emission phenomena affected by high temperatures that the acoustic emission ring count rate increases with increasing temperature and acoustic emission activity becomes more frequent in the heating process. There is a corresponding relationship between rock acoustic emission...

... stress (in the range of 30- 65 MPa) and at temperatures in the range of 250 -350 cĀ° . Assuming a power law relation between the creep rate and applied stress, values of 3.28 and 4.72 are obtained for stress exponent (n) at low and high temperatures whereas the range for Q value (activation energy...
