Study on the Underground Storage of Hazardous Waste of the Micro-seismic Signal Based on the S-transform Time-Frequency Analysis

In the disposal of hazardous waste treatment technologies due to some solid waste is difficult, costly, often stored in deep underground storage. However, the impact of surrounding rock stability of these traits would waste rock fracture can cause leakage of waste, leading to environmental pollution. Micro-seismic safety monitoring technology is an effective means to solve this problem, but to the surrounding multi-source monitoring signal is a major difficulty for signal analysis. In this paper, the optimized ST (S Transform) is introduced into the analysis of micro-seismic signal, has high-quality time domain and frequency domain information to analyze various vibration signals. The method used in micro-seismic signal processing in the underground storage of hazardous waste. The result shows that the method can be used to automatically identify and analyze micro-seismic signals.
