Abstract In order to study the precursory characteristics of acoustic emission before the peak strength and the acoustic emission characteristics of the loading-unloading process for guiding the application of AE technology in rock mass engineering monitoring and disaster warning, six kinds of rocks including granodiorite，hornfels，skarn，copper ore，wolfram-molybdenum ore and lead-zinc ore were tested respectively under uniaxial compression，incremental cyclic loading-unloading and incremental isobaric cyclic loading-unloading，and the relative tranquil period of acoustic emission before the peak strength，the AE characteristics of unloading process，the Felicity ratio under two different cyclic loading-unloading modes and changes of the load-unload response ratio were studied. The results show that some rocks always present the“relatively tranquil period”phenomenon under three different loading modes. The low frequency components of the AE events of a variety of rock samples increase significantly before failure，and the closer to the failure, the more the large amplitudes AE events. Under two different cyclic loading and unloading ways，Felicity effect occurs with Kaiser effect disappearing when the stress level reaches 50% to 60% of the peak intensity. Both Felicity ratio and load-unload response ratio are greater than 1 in the low stress level and fluctuate around 1 in the middle stress level. In the high stress level stage，the internal cracks of the rocks expand unstably with the Felicity ratio reducing and the load-unload response ratio increasing，and the samples destroy when the Felicity ratio reduces to 0.64–0.89. The Felicity ratio and the load-unload response ratio of the relatively tranquil period may be used as the parameters of rock failure prediction.
