· Blasting is only the first step in the production process for mines and quarries and the costs of this first step is normally only 8% to 12% of the total costs. The total product costs are composed of: drilling, blasting, secondary breakage of oversize, digging, haulage, crushing. Blasting affects every step in the production cycle.
· Like many chy mining phrases, "Drill to Mill," "Pit to Plant," "Mine to Mill" and "Mine to Market" are deceptively simple descriptions for complex, multilayered processes. In the mining cycle, drill and blast (DB) is arguably the first and most important step to get right. DB operations impact the entire mining process, from mining equipmentRead More
