ABSTRACT

In these years, many seismic source location techniques have been developed, such as Blake (Blake et al. 1975), SW-GBM (Salamon & Wiebols 1974), etc. These techniques needs two precondition: 1) the propagation medium of seismic wave is homogeneous and isotropic; 2) The propagation

1 INTRODUCTION

In the practice of mining and underground geotechnical engineering, the breaking of rock under high stress is always accompanied by the releasing and propagation of seismic wave. While the corresponding microseismic events have occurred, a large number of information about rock damage can be defected (Fagan et al. 2013, Chen et al. 2014). Therefore, the rock internal behavior and rockburst and other mining disasters can be inferred by a process that contains microseismic signal acquisition, processing, analysis and research. The results can help us to preventing seismic hazards; ensure the safety of deep geotechnical engineering (Wang & Ge 2008, Chen 2009).
