Product Overview
MK fully hydraulic exploration core drilling rigs are compact crawler-mounted machines developed for mineral exploration and wireline coring. Their hydraulic power heads support high-torque and high-speed drilling, while the balanced-pressure system helps control bit pressure in complex formations and deep holes.
Key Features
- Accurate coring for representative geological samples
- Hydraulic power head for torque and speed control
- Centralized electro-hydraulic controls
- Automatic pressure-maintaining drill-pipe clamp
- High-pressure mud-system option for high-solids drilling fluids
Applications and Options
Mineral exploration and wireline coring in hard rock and complex formations. Confirm core size, target depth, geology, transport access and mud-system requirement.
Review the listed mud pump, crawler type and remote-control configuration for the selected variant.
Planning An Enquiry For MK-CORE-400G Fully Hydraulic Exploration Core Drilling Rig
The following information supplements the product record. It is planning guidance, not additional model specifications or a confirmed equipment match.
Start With The Required Sample
Specify the core-sampling objective, required core size, target depth and planned hole direction. Core and RC sampling supply different sample forms; they should not be treated as the same enquiry simply because both are used in exploration.
Read Capacity With Its Stated Basis
Check the rod or drilling-system basis of any listed capacity. Identify tooling, circulation and handling requirements separately. Do not infer another size capacity from a single depth figure or a model name.
Prepare The Exploration Scope
Include the formation information, site access, working area, proposed sampling programme and existing tooling. Request the specific rig configuration and a list of rods, barrels, bits and supporting equipment to be included. Recovery or sampling results require their own site-specific assessment.
