Exploration and development of the deep part coal resource have important strategic meanings for the safety of Chinese energy. However, seismic data of deep part coal suffering from the decline of resolution. To overcome this problem, we propose a method to improve resolution of seismic data by HHT and spectrum whitening with instantaneous amplitudes of seismic signals. Compared with conventional algorithm, our method enhances every point of a seismic signal according to its instantaneous amplitude. The application results of the real data show our method could broaden bandwidths of seismic data and make strata in deep part more distinct and continuous.
