Abstract: Based on the basic principles and implementation steps of adaptive neural network（ANN),the theory and characteristics of ANN prediction of electromagnetic radiation in the process of coal and rock deformation and fracture are studied.The ANN electromagnetic radiation model is applied to predict the acoustic emission and electromagnetic radiation sequence in the process of coal and rock deformation and fracture.The results show that ANN can be used to effectively predict the electromagnetic radiation and acoustic emission signals so as to provide reliable data for judging the state of coal and rock failure.
