The invention discloses a micro-seismic
signal classification and identification method based on
deep learning, and belongs to the field of
signal analysis and identification. The method includes following steps: step 1, establishing a sample
database of micro-seismic signals and blast signals; step 2, extracting characteristics of the
dominant frequency, an after-peak
attenuation coefficient, andan energy
gravity center coefficient of sample signals, and forming a sample characteristic data
training set and a
test set; step 3, training a deep
neural network classification and identificationmodel by employing the sample characteristic data
training set, verifying a classification and identification effect of the
signal classification and identification model by employing data of the testset, and continuously improving the classification precision through crossed training; and step 4, extracting a characteristic vector of a to-be-identified signal, inputting the signal into the
signal classification model, and obtaining an identification result. The method has characteristics of
simple algorithm, high adaptability and timeliness, and high identification accuracy, the
coal mine micro-seismic signals and the blast signals can be effectively classified, and the technical value and the application prospect are very good.
