Zusammenfassung:The invention discloses a micro-seismic positioning method and a micro-seismic positioning system based on mine safety monitoring. The micro-seismic positioning method comprises the following steps: debugging a ground signal acquisition station; constructing an underground acquisition station; well-ground combined networking is carried out; arranging a detector at the optimal measuring point to acquire a micro-seismic signal; performing clustering analysis on each sampling point of the micro-seismic data by using a clustering algorithm, and separating micro-seismic data points from non-micro-seismic data points; microseismic data point signals are extracted, and noise reduction is carried out on the microseismic signals based on sliding window fragmentation; noise reduction and extraction are carried out on the micro-seismic signals by using the characteristics of low entropy and low rank of the micro-seismic signals and taking kurtosis as a judgment criterion; removing main noise components by using wavelet
