drill blast process

An integrated approach to the drill and blast process

In the mining cycle, drill and blast (D&B) is arguably the first and most important step to get right. D&B operations impact the entire mining process, from mining equipment efficiency, through crushing and grinding circuit performance, to recoveries and final product quality. Costs and energy usage increase throughout the comminution process.
