NEW METHODOLOGY TO OPTIMIZE BLASTS

摘要

The mine manager approached, bearing the news we had all been waiting for over the last few days: What was the oversize percentage from the previous blast? Our team left nearly two weeks earlier, and after nearly 30 hours of travel we arrived at the site. We spent the next two weeks in a camp in the deserts of the Middle East. We were called in for what promised to be a great challenge. The blasting on-site was producing more than 10 percent oversize, which was then being broken by a hydraulic pick before going to primary crushing - but this was if the oversize was small enough to be easily broken.
