Optimum blasting with precision delays and true bottom hole initiation through e-DET-ft at Jayant Project of NCL

摘要

Mining companies the world over are seriously looking at the 'total cost concept' having fully realized the benefits of good fragmentation and muckpile looseness achieved in the primary blasts itself. Good blast planning and accurate monitoring of the various operations holds the key to reaping and realizing the benefits. In the Mining or Construction Industry, one should look at the total cost of operations and not, in isolation, individual costs of drilling and blasting (which includes explosives and initiation system costs). Poor blast results have a cascading effect on the cost of downstream operations of loading, hauling, crushing (where applicable) and also associated aspects such as secondary blasting and slope stability. Electronic detonators are extremely important tools for tomorrow's blasting needs in varied conditions for the reason they are precise in delay timing, field programmable, and much safer to use. They can reduce mining costs, when used technically correct. They can help mines in blast control and thus meet difficult environmental conditions with more productivity.
