Summary:The invention provides a rock burst early warning method based on impact risk entropy, and the method comprises the steps: obtaining micro-seismic frequency and micro-seismic total energy through a micro-seismic monitoring means, and obtaining a shift frequency change rate and a shift energy change rate which are obtained through a rock noise monitoring means; taking the micro-seismic frequency, the micro-seismic total energy, the shift frequency change rate and the shift energy change rate as impact risk entropy indexes; determining a weight value of each impact risk entropy index by using an analytic hierarchy process on the basis of the expert scoring table; constructing an entropy increase and entropy decrease estimation model according to each impact risk entropy index, and calculating an entropy increase value and an entropy decrease value of the entropy increase and entropy decrease estimation model in combination with the determined weight value of the impact risk entropy index; and substituting the c
