ABSTRACT
A long-term research project between Brunswick Mine and the Noranda Technology Centre (NTC) was started in 1996 to develop a support system capable of withstanding rockbursts. A dynamic tendon testing facility was built and a comprehensive laboratorytesting program (Gaudreau and Basque, 1999, Gaudreau, 2000a, 2000b) led to the development of a resin-grouted, modified conebolt (MCB) that yields under dynamic loading. This new tendon was combined with retaining elements (heavy gage mesh straps
and chain link mesh) to form a Rockburst Support System. Following a series of rockbursts at Brunswick Mine, the first installation of the system began in August 2000 (Simser 2001, 2002a).
