摘要：
In this paper, the window width optimized ST (S-Transform) is introduced into the analysis of micro seismic signal, owing to the good time window adaptability and time-frequency resolution, it can provide high-quality time domain and frequency domain information to identify and analyze various vibration signals. This time-frequency analysis method is used in Lugu Iron Mine Roadway micro seismic signal processing in this study, and compared with conventional Short-Time Fourier transform. The result shows that the ST method's time-frequency spectrum features are clearer; also the quantitative values of all kinds of signal values are more accurate. It proposed a new idea for automatic identification and analysis of micro seismic signals in mine.(1)
