  • Blasthole Sampling VS Reverse Circulation Sampling ...

    2021-9-26u2002·u2002Blast Holes and RC drilling have different objectives and use different metrics. Blast holes are very short hole on a very small grid (short spacing) compared to RC drilling. But the most important aspect is that Blast holes are oriented to meet explosive and other mine planning objective. RC drilling is designed to meet geological objectives.

The air-driven piston hammer causes the bit to rapidly impact the rock while the bit is slowly turned. DTH hammers are efficient in hard-rock types. With the hammer in the hole, drill-pipe vibrations are eliminated.
