  • Optimized design of drilling and blasting operations

    2018-11-1 · 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.
