The Explosive-Free Rock Breakage Initiative

Marc C. Bétournay, Sylvie Poirier,
Abstract This presentation will highlight the First Phase of this initiative. Phase 1 will be used to develop a toolbox of non-explosive rock breaking technologies that would be available for underground development at significantly higher advance rates than, but at cost of the same order of magnitude as, drill-and-blast. Ultimately, a matrix of technologies versus best applications will also be produced. In particular, the initiative will evaluate the field performance of selected technologies, compare selected technologies to drill-and-blast extraction performance through cost benefit analyses and identify potential equipment that will carry the selected technologies.
