Micro-seismic positioning method based on improved ant lion optimization algorithm

The invention belongs to the technical field of micro-seismic positioning, and particularly relates to a micro-seismic positioning method based on an improved ant lion optimization algorithm, which comprises the following steps of: filtering seismic data acquired by a micro-seismic monitoring system; carrying out arrival time pickup of an energy ratio method on the seismic data after filtering processing to obtain first arrival time; and according to the first arrival time, an improved ant lion optimization algorithm is adopted to optimize the target function to obtain a micro-seismic source positioning position. The micro-seismic source detector can detect data of seismic waves, can perform more comprehensive analysis on information of the micro-seismic source, not only can obtain depth, but also can measure the horizontal distance from the micro-seismic source to the detector, provides reliable data for positioning of the micro-seismic source, and realizes rapid and accurate positioning of the micro-seismic
