In normal blasting all holes do not blast at the same time. Bench blasting is normally carried out as short delay blasting. The firing pattern has to be designed so that each blasthole has free breakage. The firing sequence of a chevron pattern can radically alter the drilled burden and spacing into the blasted or effective burden Be

Drilling and blasting are the two most significant operations in open pit mines that play a crucial role in downstream stages. While previous research has focused on optimiing these operations as two separate parts or merely in a specific parameter this paper proposes a system dynamic model SDM for drilling and blasting operations as an interactive system.

In these cases the firing pattern can be used to control the blast direction in a more favourable direction and improve the blasting result. Before drilling the blast direction should be set according to the orientation of the main jointing systems. Fragmentation backbreak and toe problems are all dependent upon the blasting direction.
