Abstract In the light of the characteristic time-frequency properties of different time-frequency analysis methods, it is
important to select an optimal time-frequency analysis method for high precision seismic exploration in the coal field on the
basis of comparing and studying these methods. Aimed at probing into STFT, Wavelet Transform, S-Transform, Choi-Williams
Distribution, Wigner-Ville Distribution and its improved methods, this paper studied advantages and disadvantages of every method
through numerical simulation in time resolution, frequency resolution and interference. The First Break Picking and Separate
Frequency Display for Collapse Column interpretation were realized by SPWVD and S-Transform, with a good result obtained.
