Blasthole Drilling

Our blasthole drilling can be done up to a depth of 40m using track mounted drilling rigs. Drilling diameters vary between 51mm to 165mm and is primary done in open pit or surface mines.

Controlled drilling and blasting

We are capable of doing pre-split drilling which involves drilling linear closely spaced vertical holes along the perimeter of production drilling to achieve the following when blasting:

• controlling back break
• controlling excessive ground vibrations
• filtering the effects of explosives gases from production blasts
• smooth highwall which in turn stabilizes the walls of pit and benches
• improves fragmentation on the perimeter of production blast

Added to this we do drilling and blasting of built up areas when hard rock is encountered in construction works etc
