Paper presented at the 49th U.S. Rock Mechanics/Geomechanics Symposium, June 28–July 1, 2015
Paper Number: ARMA-2015-333
... processing centers located far away from the site. The microseismic data acquired were analyzed and mapped on the 3D plan of the caverns. Statistical data analysis using source parameters of microseismic events were carried out to correlate the events with rock bolt failures in order to study the...

Paper presented at the 48th U.S. Rock Mechanics/Geomechanics Symposium, June 1–4, 2014
Paper Number: ARMA-2014-7080
... large-scale excavation response test. For both sets of data, corner Frequency ( f o ) and moment magnitude ( M w ) were found to be inside the ranges 190 kHz < f o < 750 kHz and -7.2 < M w < -6.5, respectively and all source parameters appeared to obey scaling relationships derived...

Paper Number: ARMA-08-101
... the event source parameters during the formation of this macrofracture structure, indicate following a gradual increase during loading, a fall in the moment magnitude, seismic moment, radiated energy and apparent stress, associated to facture interaction, which lead to a more substantial drop, at the...

Paper Number: ARMA-06-1024
... program is mainly geared towards short term hazard recognition and rapid relay of information to operations. Mid to long term planning/risk assessment is also conducted using both time/location of events and source parameter information. This paper gives a general overview of the Mine?s seismic monitoring...

... subsequently applied to source parameter catalogs recorded at three hard rock underground mines: Kidd, Creighton (both in Ontario, Canada), and Ridgeway (New South Wales, Australia). These catalogs contain several thousands to tens of thousands of seismic events recorded between 2001-2005 with magnitudes...
