A Technical overview of Overbreak B.O. Taiwo* Giant Miner *Graduate of Federal University of Technology Akure, Nigeria author's mail: taiwoblessing199@gmail.com Abstract: The presence of boulders in the blasted muck causes not only loss in production, but also increases the cost of hauling. In another words, the cost and efficiency of mucking, loading, and Comminution operations (crushing and grinding) will be highly altered by the outcome of blasting operation. This article give detail explanation about the causes and effect of overbreak during blasting. It point out the ways to control and minimize blast overbreak and give recommendation on the ways to improve blasting operation and safety. The safety of the mine is important to ensure guarantee of life, therefore generation of overbreak on the mine face affect both profitability and safety statu...
