The method of the invention comprises the following steps: step 1: reading a time sequence { x (t) } of a coal rock mass acoustic emission signal x; step 2: decomposing the acoustic emission signal x based on a VMD method to obtain K intrinsic modal components with frequencies sequentially arranged from high to low; and step 3: taking the high-frequency eigenmode component to perform ringing counting, namely calculating the oscillation times of crossing a preset threshold value; and 4, step 4: and taking the low-frequency eigenmode component to calculate the energy of the acoustic emission signal x. The invention can use the ringing number to represent the frequency degree of coal-rock body fracture and the energy to represent the strength degree of the coal-rock body fracture, can improve the accuracy of the representation of the damage state and the damage degree of the coal-rock body, and the sudden increase phenomenon of the ringing number and the waveform energy can be used as a precursor of coal and gas outburst and other coal mine dynamic disasters.
