| description | The invention provides a rockburst early warning method and device, electronic equipment and a medium, and the method comprises the steps: determining analysis time windows in a monitoring period, and obtaining the number of microseismic events in each analysis time window; determining a micro-seismic event quantity variance in each analysis time window, and determining a corresponding relationship between the micro-seismic event quantity variance and the analysis time; determining a microseismic event differentiation rate based on the corresponding relationship; and carrying out statistical analysis on the microseismic event differentiation rate, determining a microseismic event differentiation rate early warning value, and carrying out rockburst early warning based on the microseismic event differentiation rate early warning value. According to the invention, specific parameter early warning values can be given, and the universality and the application range of the early warning method are improved.
