The purpose of this review is to introduce the principle and development of microseismic source localization technology in deep-buried tunnel engineering.First,it introduces the main methods of microseismic source localization and the main factors affecting the accuracy of source location are summarized,including velocity structure model,propagation path of microseismic wave,objective function,algorithm,monitoring sensors array,and arrival-time picking up of microseismic wave.Then,by analyzing the influence of these factors on the result of microseismic source localization,the advantages and disadvantages of each method are discussed,and the methods and measures to improve the accuracy are counseled.This review discusses the optimization of monitoring sensors array and provides theoretical guidance for rock fracture monitoring in engineering.Finally,a brief summary is given,and the future research direction of microseismic source localization is put forward.
