Things to Consider When Buying Drilling Equipment for a Mining Site
Well, there are obviously plenty of things to consider, far too many to cover in a single article. We can simply give you some general advice and information to help narrow down your options.
We'll start with some broad questions and answers on drill rigs and then move onto an overview of drill bits.
Depending on the nature of your drilling, the bottom line is a rig that will do the job at the lowest cost per metre drilled. So...
Do you need to drill large blast holes? Rotary blast hole drill rigs have extremely high rotational torques and pull-down forces which creates high penetration rates.
Do you need to drill extensively underground? Underground drill rigs come in a vast array of heavy duty varieties from tophammer and rock support rigs to breaking drill rigs and tunnelling rigs.
Do you need a rig for exploration? Exploration drill rigs can be lightweight units ideal for core drilling or heavy duty rigs capable of both core drilling and reverse circulation drilling.
Do you need to drill straight, accurate holes? Dimensional stone drill rigs do just that quickly and safely. They can channel, line drill, split, trim and create pilot holes.
Sourcing the right drill bits will depend on the type of drilling your site plans to do – percussion drilling, diamond drilling or reverse circulation drilling.
Do you need to break the rock up while drilling? Percussion drilling does exactly that using rotating steel rock bits and a hammer action transmitted through drill rods.
Do you need the rock you cut to be blown out of the hole as you drill? Reverse circulation drills use compressed air to blast the rock cuttings away from the drill point and up the hole.
Do you need to define minerals as you drill? Diamond drilling produces core which can then be split with a core splitter or diamond saw to create samples.
