The index is an empirical method of linking geological characteristics with the effectiveness of rock-breaking with bulk explosives. The second objective was to use rock mass classification to inform perimeter blast design with the BI as an indicator of potential rock ...

In: Proceedings of Western Australian conference on mining geomechanics, Kalgoorlie, West Australia, pp 8–9 NettetA method of assessing the blastability of a rock mass is presented which makes use of five, readily available, simple parameters. These are the Rock Mass Description, Joint Plane Spacing, Joint Plane Orientation, Specific Gravity Influence and Hardness. For a particular rock mass a value is assigned to each parameter and the Blastability Index … hot vic motorcycle parts
