In order to study the fractal characteristics of acoustic emission with different damage degrees in the uniaxial compression process of coal samples with impact tendency. the uniaxial compression test is carried out on the impact-prone coal. the damage model of acoustic emission ringing count and the fractal dimension calculation model of the time series of acoustic emission parameters are used to study the damage evolution in the process of coal sample failure and the fractal dimension of different damage degrees. The research shows that whenever there is a large rupture of coal samples,the acoustic emission will increase gradually. The generation of large ringing count is the result of energy release during crack propagation and aggregation. Most of the frequent acoustic emission phenomena of impact coal occur in the later stage of the whole process of stress-strain; the damage strain process of coal samples can be divided into three stages: initial damage stage,damage evolution stag
