After speaking with Dyno Nobel, the mine decided to implement BlastWeb®, a centralised blasting system that is specifically designed for use in underground mining operations. BlastWeb allows reliable remote initiation of development, production and stope blasting from a safe and controlled location on the surface. The blast areas can be completely evacuated as no-one is required to be underground for the blasting. In addition to the obvious safety benefits, the other main benefit of the system at this mine is a reduction in the re-entry time. After the implementation of BlastWeb, a comparison was made of the blast completion times before and after its introduction. It was determined that centralised blasting reduced the blast completion time, on average, by 10 minutes. The implementation of Dyno Nobel’s Centralised Blasting System supports both the safety of the mine employees during blasting and an increase in production time.
