Blasthole drilling
Production drilling of blastholes in quarries and mines.
There are four main types of blastholes:
Production holes
Pre-split holes
Buffer holes
Production holes underground
Well drilling
There are two main purposes for well drilling:
Waterwells
Geothermal wells
The required depth and size of the wells varies geographically due to pump standards and geology.
