Possible ways of optimizing blasting operations using O-Pitblast software

Abstract

Blasting is one method of mining solid rock masses. The operation parameters, i.e. burden, blast hole and row spacing, stemming length, subdrilling length or explosive charge mass per single delay and total explosive charge mass per series, must be determined. The determined parameters can be optimized taking into account both technical and economic performance, using a dedicated software with an optimization module. The article presents different ways of improving and optimizing blasting operation parameters using O-Pitblast software and the effects of these improvements on planned blasting operations.
