In mineral exploration, drilling depth alone does not determine project success.
The quality and continuity of the recovered core are often more important because geologists rely on these samples to understand underground formations.
A full hydraulic wireline core drilling rig gives operators greater control over the drilling process.
Recovered core can provide information about:
Rock type
Mineralization
Fractures
Structural characteristics
Formation boundaries
Geological changes
Poorly recovered or heavily broken core can reduce the value of this information.
Diamond core bits cut rather than hammer the formation.
Stable rotation helps maintain controlled cutting conditions and can reduce unnecessary vibration.
Excessive feed may overload the bit or disturb fractured formations.
Insufficient feed can reduce cutting efficiency.
A hydraulic feed system allows the operator to adjust drilling conditions as geology changes.
Once the inner tube is filled, the wireline overshot retrieves it through the drill rods.
This eliminates the need to pull the complete drill string for every normal core recovery cycle.
The result is especially valuable in deeper boreholes.
Good core recovery depends on more than the rig.
The complete system includes:
Diamond core bit
Reaming shell
Core barrel
Inner tube
Drill rods
Drilling fluid
Operating parameters
A suitable hydraulic drilling rig provides the controlled platform required to operate these tools effectively.
YKDRILL serves international geological exploration and drilling markets with drilling equipment and supporting drill tools.
For exploration companies, improving core recovery means obtaining more useful geological information from every meter drilled.
