BLASTING: EVOLVING FROM AN ART INTO A SCIENCE

摘要

The words "blasting" and "precision" generally aren't found in the same sentence-or for that matter, even in the same paragraph-when the subject is mine operations. But, according to blasting experts, there's no longer any reason for the two terms to be mutually exclusive when it comes to production blasting at both surface and underground sites. control, overbreak damage, and, in particular, proper material fragmentation. "We do a lot of work with mines to ensure that they have the correct fragmentation profile for the types of [processing] circuits at the mill." Achieving a successful solution to a blasting problem doesn't involve a lot of mystery, he explained. "We recommend a well-structured, project-managed approach, starting with a sit-down with the customer to identify and define the problem. We would like to receive, or be able to obtain, current data about the mine operation. If you don't know what's happening right now, there's no way you can reliably gauge the results of changes to the system. You have to establish a baseline to work from."
