Drilling and blasting operations are one of the most important mining processes in open pit mines which encompass the crucial part of mining costs. Today, despite the development of mechanized drilling in surface mining, blasting operation has remained as an inseparable part of mining operations in most open pit mines. This paper tries to develop a mathematical model for finding an optimal length and width of the blast block for minimizing drilling and blasting costs in open pit mines. With the approach, the most ...
