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.countryscenesaddleryandpetsuppliers.shop/product-category/compositi-matrix-toe-cage/
