Application of rock mass classification and Blastability Index for the improvement of wall control: a hard-rock mining case study
Conventional blasting rules of thumb used to develop blast designs are based on parametric ratios, with insufficient consideration of the rock mass factors that influence the achievability of final wall designs. At a hard-rock mine in Botswana, catchment berm designs were frequently unachievable, wh...
