... ABSTRACT: In order to understand how the rock mass evolves with extraction in the particularly highly-stressed environment of a sill pillar in a hard rock mine in North America, we investigate the utility of seismic tomography as an interpretive tool. We use a rich dataset of blasts...

... the formation of the liquid saturated zone and the distribution of the seismic and aseismic deformations. First, we present the Northwest Geysers EGS Demonstration project, a 3-D seismic tomography performed during the first months of injection and the microseismic activity by using the Seismicity-Based...

... conditions at this underground longwall mine: a microseismic monitoring network, a seismic tomography system and a longwall shield-leg pressure recording system. Results from the monitoring systems were correlated in an effort to determine whether the diverse information could be used synergistically...
