Design Process In Open Pit Mining

Nov 01 2018 drilling and blasting are the two most significant operations in open pit mines that play a crucial role in downstream stages 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
