Blast furnace hydraulic rock drill production standards

What is a blasthole rig & Drill?

Blasthole rigs and drills don’t need much explanation. They’re used for drilling a hole into the surface of the rock, packing the hole with explosives and then detonating those explosives in the blasthole to break up rock and hard minerals to make it easier to remove.

Should drilling and blasting be performed under the same supervisor?

Operations where drilling and blasting are performed under the same supervisor or by the same crews are highly recommended, in that this allows both crews to work closely to maintain efficient borehole drilling and loading. Drilling information can be conveyed from the drilling crew to the blasting crew by means of stakes placed at each blasthole.
