WebMining Optimization Laboratory (MOL) University of Alberta, Edmonton, Canada . Abstract Long-term mine scheduling is among one of the optimization problems. Block caving technique is a mass mining method in which gravity is used in combinationwith internal rock stresses to fracture and break the rock mass into pieces that can be handled by miners. WebThe blast would undercut the ore, caving toward the drawpoint at the bottom. Because mining starts in the raises rather than in drifts, no personnel are exposed to drilling and blasting. By reducing the need for drifts, infrastructure requirements ahead of mining can also be reduced by a colossal 50%, which not only speeds the time to ore but ... chrome pc antigo
