Paper abstract
The aim of this article is to present an application of wavelet transform for P phase arrival detection in seismic signals from Polish coal-mines. The main idea is to use this methods to low amplitude, therefor noisy seismic signals. We can use the fact that the begining of P wave of the seismic signal can appear in the wavelet coefficiens across several scales. In this article the method is presented that locates these arrivals in one-component seismic signals.
