Raise Drill

For over 40 years, the Redpath raiseboring manufacturing team has continued to innovate, develop and deliver the latest technology to the mining industry, resulting in the Redbore family of raise drills. The Redbore fleet includes the Redbore 30, 35, 40, 50, 50X, 60UR, 65, 70, 80 and 90, as well as the world’s largest proven capacity raise drill, the Redbore 100.

The Redbore 80 is a mid-sized raise drill ideally suited for surface and underground raises, ore and waste passages, along with infrastructure raises in the 13’ (4 m) diameter range, with depths up to 1500’ (457 m).

The Redbore 70 is a powerful and compact raise drill designed to fit in smaller excavations. The Redbore 70 can be configured to complete 48″ (1.22 m) diameter downreaming. Nominal capacities range up to 13’ (4 m) diameters with lengths of raises up to 2,000’ (609 m).

The Redbore 60UR has been specifically designed to meet industry demand for larger upream holes (blindhole or boxhole) while maintaining a low machine profile. This allows mine operators to improve productivity by achieving more versatility in block cave design.

The Redbore 50X has been specifically designed for upreaming (blindhole or boxhole) while maintaining a low profile. It is also capable of completing conventional raises. This innovative unit features a retractable wrenching arm, lay-down rod handler, and a drive system with greatly improved transfer of energy, requiring less power during operations.
The Redbore 50 has been designed as a mid-capacity drill whose role is to replace much larger equipment. The Redbore 50 has the same footprint as the Redbore 40 and requires only slightly more back height. 
The Redbore 40 is a small and compact drill designed primarily for production slot programs. The drill can be configured for downreaming at 28 1/2″ (724 mm), eliminating the need for bottom-hole access. Nominally, the machine is capable of reaming 60″ (1.52 m) diameter holes, up to 500’ (152 m) in length.
The Redbore 30 was designed specifically for rapid boxhole development. It is the lightest, most compact drill in the blindhole and boxhole market. The drill’s energy efficient power pack and operating console have been combined, making this unit a highly mobile and productive package. The machine is equipped with loading pockets and can be moved by most underground scoops and loaders, which greatly minimizes collar-to-collar downtime.
