Improvement of blasting operation in Sukari surface mine

الملخص EN

Detailed blasting data had been collected from Sukari gold mine.

These data were arranged and
computerized to feed a simulation software.

DNA i-Blast is one of the powerful software for
simulating, analyzing, and prediction the blasting products.

As fragmentation is the main effective
parameter of blasting, so we focused on the fragmentation size distribution according to Rosin-
Rammeler equation.

To assure the output size, an analysis for real fragment images was carried
out and it gives almost the same results.

According to simulation results, two improvements in
blast-hole design are suggested.

First suggestion is using air-deck of 25% of the charge column,
and the second is using denser explosive.

One of these suggestions or both of them can be applied
and gives obviously reduction in the particle sizes.
