Possibility of more precise analytical prediction of rock mass energy changes with the use of passive seismic tomography readings

Abstract

Selection of rock layers, which deformation is linked to changes of tremors and rock burst hazard status, becomes a common problem during the application of analytical prediction methods. The article presents a possibility of more precise analytical prediction of potential tremor hazard formation during mining exploitation, based on passive seismic tomography results. With a use of exploitation area model, utilization possibility of longitudinal wave’s velocity field was presented, which is determined based on tremors recording used for rock stratum selection, in which occuring energy processes may have fundamental influence on the observed seismic and rock burst hazard level.
