42nd Annual Conference

A Case Study Applying the Multiple Blasthole Fragmentation Model (MBF) at an Open Pit Mine (Room Concorde A)

02 Feb 16
8:30 AM - 9:00 AM

Tracks: FRAGBLAST: Modeling and Image Analysis

Speaker(s): Ruilin Yang, Orica USA Inc

Near field vibration measurements from signature hole blasts were conducted to obtain near field vibration attenuation parameters and the ground sonic velocity. A production blast was monitored with the fragmentation being measured. Such information is site specific input to the MBF model. Various blast design scenarios were simulated.
