Abstract

This chapter introduces a method, combining the microseismic muti-parameter and tomography for early warning of rock instability in underground mining. The microseismic monitoring data is employed and the microseismic sources are determined using the velocity-free localization method. Based on the location result, tomography analysis is conducted for several layers. Taking into account the indication of the tomography results, multi-parameters, in-site surveys, mining parameters, and records of daily works, the rock instability risk is evaluated.
