Discriminant Model of Coal Mining Microseismic and Blasting Signals Based on Waveform Characteristics
Generally, there are two important types of microseismic (MS) signals caused by mining and blasting activities at coal mines. The waveform characteristics of MS signals using FFT, STA/LTA method, and envelope analysis were studied to distinguish these two types of MS signals. The main results are as...
