摘要：
Initial results of processing of mining induced seismic events are presented. In this contribution, the discrete wavelet transform is applied to the construction of a 3-dimension mapping of the time-frequency decomposition. Spatial mapping of results is used for concise presentation and for the type analysis of the decomposed wave pattern and for the evaluation of the prevailing frequency in the analyzed part of signal. The wavelet transform is also applied to the smoothing of recorded signals.
