As the mine accidents happen frequently in recent years, the detecting technology for microseism becomes much more important. However, there is no advanced microseism detecting system at home. It's pretty important for microseisms denoising and Reversion. A wavelet denoising method is presented here to process microseism signal, and the microseism record can get high signal to noise ratio. Meanwhile based on the software of LabVIEW, s design of real-time detecting system for microseism based on virtual instrument is presented. The advantage of the virtual instrument was sufficiently exerted to achieve the real-time detecting and analyzing of the microseism.
