摘　　要：微震监测技术是一门新兴的地球物理实时监测技术,其研究工作主要集中在微震震源定位方法和微震信号初至拾取两个方面:定位方法以经典的Geiger法以及在此基础上发展的各种线性、非线性微震震源定位方法为主;STA/LTA法、AIC法、分形维数法和小波变换法是微震信号初至拾取的主要方法。目前,矿山领域将微震监测技术主要用于冲击地压、突水等灾害的预测预报;矿山微震监测技术在提高震源定位精度、数据精细化处理等方面还有待加强,从基础理论研究、数据信号处理和仪器研发等方面对矿山微震监测技术进一步研究和发展方向进行了展望。Microseismic monitoring technology is a new geophysical monitoring technology whose theoretical research mainly is focused on the source location method and microseismic signal recognition.All kinds of linear and nonlinear localization methods are developed based on the classical Geiger method.STA/LTA,AIC,fractal dimension and wavelet transform is the main method of microseismic first-break picking method.Microseismic monitoring is widely applied in mining engineering fields,such as rock bursting and mine water inrush disaster prevention and forecast.Mine microseismic monitoring technology needs to be strengthened in the improving source location precision and data refinement processing,The mine microseismic monitoring technology further research direction was prospected from the of basic theory research,data signal processing and Instrument research.
