Study on Synergetic Characteristic of AE Phenomenon in Rock Failure Process
Synergetic characteristic of AE in rock failure process is studied by synergetics and RFPA2D. The synergetic effect is validated by both the theory analysis and numerical experiment. The synergetic characteristic of AE in rock failure process is analyzed by researching the relationship between inner state change of the structure and Ae characteristic. Realize the laws of rock failure on higher level, and discuss the synergetic characteristic effect of AE instructively. Firstly, establish the equation of AE evolvement with the order parameter of AE counts based on slaving principle of synergetics. Then get the stable and unstable solution of this equation, analyze their science physical meaning, and discribe the synergetic phenomenon of rock AE entirely. At last, simulate the AE phenomenon of rock failure with RFPA2D and validate the synergetic phenomenon of rock AE with numerical experiment Further more approve the veracity of research results and the feasibility of studying rock AE. The results are useful in forecasting the trend of rock stability before failure and can be used in directing stope safety and laneway surrounding rock stability control.
