The second and third generation of non-dominated sorting genetic algorithm(NSGA-Ⅱ, NSGA-Ⅲ), multi-objective grasshopper optimization algorithm(MOGOA), multi-objective gray wolf optimizer(MOGWO), multi-objective ant lion optimizer(MOALO), and multi-objective evolutionary algorithm based on decomposition(MOEA/D) are introduced to construct multi-objective localization optimizations functions using two different classical microseismic inversion mathematical models. Based on the comparative testing of microseismic event data in deep-mining mine and manual simulation data, the effectiveness and reliability of six multi-objective localization algorithms are analyzed. The results show that the performance of six multi-objective localization models varies. The mean error of 100-round microseismic source localization of MOALO based on the polyhedral array simulation is 1.242 5 m, while the mean error of microseismic source localization of NSGA-Ⅱ based on deep-mining mine is 162.569 1 m. The robustness of MOGOA, based on Shizhuyuan mine microseismic event, is superior to that of MOALO. Considering multiple performance indices, including localization accuracy and model reliability, it is believed that MOGOA has strong application prospects for engineering physical exploration and microseismic monitoring.
