The comparative investigation of the characteristics of deformation and AE were conducted and the results are presented as followed: 1. The characteristics of rock AE are correlated to the strength, joints, cracks, and the size and hardness of crystalline grain. 2. The sequence of AE can be divided into four phases: beginning phase, tempestuousness phase, drop phase and dreariness phase. The loss and the duration of the phases are correlated to the rock character and flaws in the rock. 3. The AE rate characteristics are not almost concordant with the AE energy rate. 4. Besides the homogeneity, the strength of rock contributes the activity of AE. The higher the strength is, the lower the activity is. 5. There is a dreariness phase before the failure of most kinds of rock. 6. Whether the precursor is obvious is correlated to rock the character, and the precursor of AE rate is more apparent than the precursor of AE energy rate comparatively.
