The paper mainly describes the development of domestic and foreign microseismic monitoring technology in locating and engineering application, and highlights the engineering application and new advance of the microseismic technology in deep mining. It is pointed out that the key and main research points in the future microseismic monitoring technology for well interpreting and handling mining-related issues are:to develop a rapid microseismic positioning method which can satisfy the requirement of accurate locating of mine rockmass rupture, to make dynamic tracking monitoring of the threedimensional fracture of rock stratum and coal seam in mining process, and to study the internal law of rockmass rupture field and mining stress field so as to solve the problems in forecasting mine dynamic disasters such as rock burst, coal and gas rush. The recent research achievements in these aspects are also presented.
