Diamec MCR core drilling rigs

Short holes means many movesWhen defining ore content in under-ground mines, a big part of the job is to move the core drilling rig from site to site. Ore definition drilling means shorter holes in many different places in the mine, and the core drilling rig needs to shift place frequently.

To move a traditional rig often inclu-des disassembling of control unit and power pack to enable a move. This of course takes up valuable time, and the risk for damage and damage errors when moving and reconnecting the components is not negligible.

Self sufficient, no disturbanceAlso, when a traditional core dril-ling rig is to be moved, the regular mining operations has to be disturbed as assistance is required for lifting and transporting the rig. To the exploration driller, this often means waiting for availability of mining equipment, and the move also takes away valuable time from the mining operation.

The Diamec Mobile Carrier Rig (MCR) combines the best of two worlds: the high productivity and accuracy in core drilling of a Diamec core drilling rig, with the robustness and mobility of a Simba carrier! This combination provides the exploration driller with unmatched productivity in underground mining.

Move fast - drill fastThe Diamec MCR is completely self sufficient and can swiftly move from one drill spot to another. The time saving can be more than 50% depending on distance etc! Less people and equipment needs to be involved, and the entire core drilling equipment is moved in one piece. Setting up for next drill hole is done within minutes.

Less downtime of course means hig-her productivity. This is also the case for the Diamec MCR, the idea is that when moving move it fast, when drilling drill fast!

Mobility

Better reach, higher efficiencyThe Diamec MCR does not only drill and move quickly it has also an improved reach, with access to wider angles.

The 1.8 m feed frame gives a superior stroke length, and ensures that the exploration driller can maintain highest possible efficiency when retreiving core samples for the mine.

Productivity

Heavy drilling requires a robust carrierCore drilling is heavy drilling, and this requires a strong and robust carrier. We found this in the well proven Simba production drill rig. Combined with the Diamec, we have the markets most reliable solution for mobile core dril-ling. All components are built with a high level of engineering in them, and combined with the optional Diamec APC control system, productivity can reach new heights.

Touch screen computerAPC uses the latest in computer tech-nology. Based on Atlas Copcos field-proven RCS-technology, APC is the most user-friendly and efficient system on the market today. All relevant infor-mation is displayed on a touch screen that enables the selection of the right parameters. Theres a separate menu for drilling, rod running and wire line operation. Whats more, theres a built -in operators manual and if need be a manual override.

All the operating data is saved and diagnosed, or can be downloaded onto a USB memory stick for future analy-sis by external computers.

APC - Your drilling supervisorWith the APC, the drilling operation is supervised by a computer. Once youve entered the key parameters, the APC computer assumes control in order to maintain a constant penetra-tion rate. The system reacts instantly to the slightest change in rock formation, adjusting feed force, or torque accord-ingly. It can even shut down the rig if necessary.

Using an APC control while drilling, also provides efficient rod handling, improved bit life, less core blockage and minimum deviation. Not to men-tion fewer human errors.
