Geomachine Geological boom / diamond coring equipment

Geomachine’s diamond coring equipment is designed for ore prospecting and can be used for sampling from both soil and bedrock. Still, for rock sampling, geological drill booms must be equipped with a higher-speed diamond coring chuck, a bottom brake designed for diamond coring and a roller lift.

The chuck’s maximum outer diameter of 77.5 mm enables drilling with various equipment. Wireline equipment can be used with an extension boom mounted on the boom. The correct rotation head torque and speed are selected based on the equipment specific rotation speed requirements and the target drilling depths.

Geological booms also have a dual drill table, allowing the other drill line to be used, e.g. for auger or percussion drilling. Switching between the methods is fast.

The boom can be mounted on Geomachine GM100 or GM200 drill rigs. Diamond coring rig is also always equipped with a convenient work platform and a safety cage, which enables drilling at different angles according to the customer’s sampling needs. Like the geotechnical booms, the diamond coring equipment can also be installed on customer-specific carriers as long as they have sufficient hydraulic output.

The booms are controlled electronically, and all survey data can be stored in the GMTracker DTH data-logger software. The results and coordinates can be shared via the GM cloud service.
