Rock burst early warning method based on micro-seismic accumulated energy

The invention discloses a rock burst early-warning method based on micro-seismic accumulated energy, which comprises the following steps of: collecting coal stress early-warning monitoring point monitoring data of a working surface with serious mine impact, drawing a change curve of the monitoring data of each stress early-warning monitoring point along with the distance between the stress early-warning monitoring point and the working surface, and counting the micro-seismic event accumulated energy near each stress early-warning monitoring point; combining the distance change curve with the accumulated energy, analyzing correlation of the distance change curve and the accumulated energy, judging whether the experimental mine needs early warning or not, collecting an accumulated energy threshold value of the sample working face and energy values of other working faces if early warning is needed, and taking danger relieving measures when the energy values of the other working faces are not smaller than the acc
