big bench blasting in mining operations The economic analysis of the use of explosives is an important part of blasting operations in mining and construction Explosives are energy and the efficient use of this energy is a major factor in keeping rock blasting costs under control Highenergy explosives enhance fragmentation which ultimately Drilling and blasting are the two most significant operations in open pit mines that play a crucial role in downstream stag While previous research has focused on optimizing these operations as two separate parts or merely in a specific parameter this paper proposes a system dynamic model SDM for drilling and blasting operations as an interactive system
