Abstract: To predict the tendency of coal mine rock burst accidents as early as possible and to make timely and accurately rock burst prevention measures, the electromagnetic radiation method of improved PSO-BP model is studied to predict the tendency of rock burst. The improved method of predicting coal mine rock burst theory and original PSO-BP model is studied by studying the electromagnetic radiation method. The improved PSO-BP model is applied to the evaluation of rock burst, and field practice is carried out at 1316 working face. Three large-scale shocks are accurately predicted, and the accuracy of accident prediction is 100%.
