In order to study the acoustic emission and fractal characteristics of coal rock under uniaxial compression,an experimental study was carried out to investigate the acoustic emission and fractal characteristics of sandstone,sandy mudstone and group Wu coal samples by using RMT-150C rock mechanics test system and CDAE-1 acoustic emission instrument.A contrast study was carried out on mechanical properties,acoustic emission count,cumulative count and acoustic emission sequence fractal characteristics of sandstone,sandy mudstone and group Wu coal sample.The results show that the complete stress-strain process of coal and rock was divided into four stages: initial consolidation phase,quasi elastic stage,plastic deformation stage and residual deformation stage.In the initial consolidation phase,the acoustic emission count is small and the trend of cumulative count increase is very slow.In quasi elastic stage,the acoustic emission is increased,and increasing trend of cumulative count is fast.In plastic deformation stage,the jumping up phenomenon of the acoustic emission count appears and surge phenomenon appears for the cumulative count and for the sandstone,it is particularly evident.In the residual deformation stage,the acoustic emission count is very small,and cumulative count did not increase.Acoustic emission sequence have fractal characteristics in the process of the coal rock failure.It can serve as precursors to forecast coal rock dynamic disaster based on that the fractal dimension value will have dump phenomenon in the process of coal rock failure.
