    1. Introduction. Mining activity is mostly represented by these four main operations drilling blasting loading and hauling. For a proper mine planning and design all of these operations need to be carefully planned in such a manner that can prevent extra loads such as operating costs environmental footprints etc. Amongst these operations drilling and blasting are known as the pioneers 1. Introduction. Rock fragmentation distribution influences a range of mining and milling processes including load and haul rates crushing and grinding performance and ore recovery in beneficiation processes (Michaud et al. 1997) opencast mining where blasting is employed for excavation the overall cost effectiveness of the production operations is compatible with optimization of
