Validating a support performance database based on passive monitoring data

This paper reports on an on-going analysis of support performance at Vale’s Creighton Mine covering the period from January 2000 to September 2011. A database was constructed of 133 rockbursts and the associated damage to support systems at 191 locations. The main source of information has been obtained through the seismic systems and on-site assessments. This work validates the information collected on site in order to quantify the performance of different support systems in a seismically active mine.
