Abstract In response to the frequent occurrence of high-energy microseismic events in coal mines in China. a back propagation neural network (BPNN) prediction model based on surface subsidence data has been proposed to provide a basis for safely and efficiently predicting coal mine disasters. Theoretical research on the relationship between surface displacement. mining disturbance. https://www.bekindtopets.com/flash-find-Winmau-Firestorm-Steel-Tip-Darts-24gm-special-save/
