The blasting operation plays a pivotal role in the overall economics of opencast mines. the blasting sub-system affects all the other associated sub-systems, i.e. loading, transport, crushing and milling operations. fragmentation control through effective blast design and its effect on productivity are the challenging tasks for practicing blasting engineer due to inadequate knowledge of actual mining.
