Full family integration, enhanced Cat technology maximize value of the Cat® MD6310 rotary drill


For Release Worldwide: September 2021
Release Number: 781PR21

Part of the Cat drill family, the Cat® MD6310 rotary drill on display at MINExpo 2021 shares a common platform, parts, components and technologies across the entire drill line to maximize lifecycle value and streamline operator training, maintenance strategies and fleet planning. Matched to the application, its powertrain optimizes system efficiency to deliver higher performance with reduced fuel burn.

Every component and subsystem on the MD6310 – engine, compressor, hydraulics and undercarriage – are purposely selected and properly matched to work together as a system, resulting in increased uptime, greater efficiency and low cost-per-meter drilling. The proven Cat electronics infrastructure, shared across Cat machines for technician familiarity, boasts integrated protection features and interlocks to prevent potential failures or misuse and improve operating safety.

The drill’s new electronic compressor regulation boosts productivity while reducing fuel burn. Modulating working pressure and air volume flow, the compressor controls match the drill’s compressed air output to the specific application, tooling and how it interacts with ground conditions.

Leveraging automation

New MD6310 rotary drills integrate Caterpillar electronics that leverage automated features and technology to improve drilling accuracy and efficiency. Drill Assist executes all major functions or cycles of the drill and automatically adapts drill power to match ground conditions. Automated features such as jack leveling and retraction, mast raise and lock to desired angle, and auto pipe handling for multi-pass auto drill-to-depth improve operator drilling efficiency on the bench.

Cat® MineStar™ ready, the drill’s electronics infrastructure provides a gateway to exclusive Caterpillar technologies that further advance drilling automation and safety. Terrain for drilling uses high-precision GPS guidance to deliver accuracy down to the centimeter, ensuring holes in the pattern are drilled in the right place and to the designed depth.

As a building block to autonomy, Command for drilling offers scalable technologies ranging from line-of-site remote control to autonomous operation to meet the mine site’s needs for safety and productivity. The remote operator’s station removes the operator from the bench and now allows one operator to manage drill operations and run up to five machines simultaneously. As part of the MINExpo display, the Cat Command Station gives show attendees the opportunity to experience the capabilities of Command for drilling’s remote operation.

Lower costs, improved safety

Advancing sustainable operation while lowering owning and operating costs, major components for the MD6310 – engine, undercarriage and rotary head gearbox – are built to be rebuilt, giving the machine multiple service lives. Common components and consumables across the Cat drill family reduce parts inventory needs and simplify service.

Onboard health monitoring and Cat Electronic Technician makes troubleshooting quick and convenient to increase drill uptime availability. Uniform hose and wiring harness routing increases machine reliability in the field. Grouped service points and simplified access to maintenance items reduce service time, allowing the MD6310 to spend more time in the field and less time in the shop.

Designed to improve safety and operator comfort, the next generation cab features floor to ceiling windows to improve line-of-sight to the drill deck and offers ergonomic display and control layouts. Closed-circuit cameras with additional mast camera help to improve operator visibility. Its FOPS-rated cab, standard drill window safety cage and operator-present conditional safety interlocks help further improve safe operation.

Ideal for high-production drilling on 12- and 15-m (39.4- and 49.2-ft) bench heights and capable of drilling up to 311-mm (12.25-in) hole diameters, the MD6310 offers up to 30-degree angle hole drilling for cast blasting. A true global machine, the MD6310 is powered by the Cat C32 engine with configurations available to meet EU Stage V and U.S. EPA Tier 4 Final or Tier 2-equivalent emissions standards. A 42.2 m3/min (1,500 ft3/min) @ 34.4 bar (500 psi) compressor is available for DTH drilling, while rotary drilling compressor choices include units offering 56.6 m3/min (2,000 ft3/min) @ 8.6 bar (125 psi) or 73.6 m3/min (2,600 ft3/min) @ 7.6 bar (110 psi).
