AE is an indicator of rock mass fracturing. Synergetics is used to study the AE characteristics in the rock mass fracturing process. The laws of rock mass fracture are further studied through the relationship between AE and damage evolution. AE count rate is taken as the order parameter to study the rock mass failure process. Firstly, the evolutionequation of the AE order parameter is established according to the relationship of AE and damage. Secondly, solutions of stationary state and nonstationary state are obtained and analyzed. The synergetic characteristics of AE are described in generalities. At last, the AE phenomena of rock mass break is simulated with the RFPA software. The synergetic effects of rock mass AE are verified through numerical simulation. The suitability of the AE technique for rock damage process analysis was further demonstrated.
