Cost-effective Drilling Comes at a Price—But Pays Big Dividends--Recent conference highlights the information needed to plan, drill and shoot efficiently

摘要

The success or failure of an individual blasthole to achieve its intended effect doesn't carry much statistical clout in a blast pattern comprising up to 1,500 holes, or at a mine that routinely conducts multiple daily blasts—or across a global industry that measures total daily blasthole production in the five-figure range or higher. It's only when the reasons for consistent drilling and blasting (D&B) success or failure become systemic to an operation that a noticeable change in productivity becomes apparent, occasionally leading to spirited discussions within and between mine departments about "what are we doing wrong?" or much less frequently, "What are we doing right?"
