Characterization of underground rock fragmentation

Singh, A. / Scoble, M. / Lizotte, Y. / Crowther, G.

Summary This paper focuses on the methodology and techniques developed to characterize the rock fragments produced by blasting in an underground environment. This work formed part of an integrated approach to the optimization of blasting design at a Canadian mine. Details are given of the photographic and image analysis techniques adopted, together with data from a program of full scale, study blasts in the mine. Features of the observed fragmentation are reviewed which related to controlled variation in the blast designs, together with other factors which were observed both to influence fragmentation characteristics and to interact with loading equipment productivity.
