A case study is presented using Northparkes Mine microseismic (MS) events located by forward calculating P- and S-wave travel times using ray-tracing and wavefront construction techniques through velocity structures that mimic heterogeneity and damage in the ...

Erosion of rock cliffs has been considered to be relatively unpredictable. This perceived stochastic nature of the erosional processes often occurs through collapses along fractures in the rock-mass. The prediction of catastrophic cliff failures and collapses ...

This paper addresses application of microseismic event monitoring system in excavation of highly stressed rock mass in underground oil storage caverns. The locations and magnitudes of microseismic events were determined using a network of 12 uniaxial sensors. ...

The implementation of routine real-time micro-seismic monitoring of open pit mine slopes has been discussed. Some examples of seismic arrays have been given, and a recommendation of suitable seismic sensors made. Unfortunately near-surface sensors are required ...

The National Institute for Occupational Safety and Health (NIOSH) evaluated microseismic activity from three field sites to compare and contrast the characteristics of microseismic emissions from very different geologic, stress, and mining environments. Recently, ...

Numerical simulation of seismoacoustic emission (SAE) associated with fracturing in zones of shear stress concentration shows that SAE signals are polarized along the stress direction. The proposed polarization methodology for monitoring of slope stability ...
