1.Blast with
Raydiet resulted in 19.25% reduction in digging time, 12 % in loading time and
7.27% in total cycle time of shovel operation.
2.Number of
Boulders reduced by 33% in blasts carried out with Raydet.
3.Average Fragment
size reduced by 31% in blasts with Raydet – (using Digital Image Analysis).
4.Noise levels
reduced by 10% with Raydet.
5.Fly rock was
minimal and at times NIL with Raydet.
6.Blast with Raydet
resulted in compact muck piles, as against more those observed with detonating
cord initiated blasts.
7.Video analysis in
indicated better utilization of explosive energy, without loosening of stemming
zone, as was the case with detonating cord. (A non-electric delay detonator)
