YG RC Drilling Rig
RC drilling uses a dual-wall drill pipe system (outer pipe + inner tube). Compressed air drives a tungsten carbide hammer bit to crush rock formations. Unlike diamond drilling, RC collects rock cuttings (not core samples).
How It Works:
1
The pneumatic hammer repeatedly strikes the bit, breaking hard rock.
2
Air pressure creates reverse circulation, forcing cuttings up through the inner tube.
3
Cuttings exit via a hose into a cyclone separator for sampling.
4
Bagged samples (labeled with depth/location) go directly to the lab.
