RAISEBORING From management consulting and operations personnel, to in-house engineering and service technicians, Redpath offers full turn-key raiseboring contracting services. Through our ability to successfully and safely complete raiseboring assignments under difficult or unusual conditions, the Redpath Raiseboring team offers honed skills and experience that are indispensable for clients considering raiseboring projects of any scope. Contracting experience, combined with manufacturing and service capabilities, enable Redpath to provide a level of service unparalleled in the industry. Each raise drill is designed and built by raise drillers for raise drillers. Whether small or large diameter openings, Redpath meets the demand for ventilation raises, production shafts, pilots for slashed and raised shafts, escape manways, fill raises, ore and waste passes and slot raises.

Meeting the Challenge Safety - First, Last and Always is the guiding principle by which Redpath operates and we endeavour to make every Redpath job a safe one. Everyone at Redpath has a responsibility to each other and themselves to work safely.

To provide the mining industry with a level of service that will exceed normally accepted standards is the philosophy applied on all Redpath projects. A quality product from concept to completion is the result of this commitment. We believe that respect for our natural environment is paramount to the success of The Redpath Group and our industry, and we take the necessary precautions for its protection. As Redpath faces the challenges of the future, our commitment to safety, quality and the environment will continue.

MANUFACTURING The development of the Redpath Redbore raise drill is one result of innovation born from the determination to meet specific challenges and fill the client’s needs. From the original Redbore 40 to the Redbore 100, The Redpath Group is pleased to present its Redbore family of raise drills. For over forty years, the Redpath raiseboring manufacturing team has continually innovated to develop and deliver the latest technology in the industry, resulting in the Redbore family of raise drills. The fleet has expanded to include the Redbore 30, 40, 50MDUR, 50, 60, 70, 90 models, alongside the world’s largest capacity raise drill, the Redbore 100. The Redbore fleet of raise drills are capable of handling a full-range of diameter and depth of openings; our raise drills are acclaimed for their unique power output and compact design. Redpath is the only Canadian manufacturer of raise drills which has grown to earn the title of being the largest manufacturer in North America. With the most reliable parts inventory available worldwide, Redpath is one of the few manufacturers that offer a reliable, dedicated team of

on-hand qualified designers and technicians. Redpath provides assistance and expertise to clients using a custom built training program designed to assist clients train their operators and maintenance personnel comprehensively and safely. The raise drill manufacturing team is equally capable to service all makes and models of raise drills, including the design and manufacture of new efficient systems to upgrade older equipment when required. With one of the most extensive fleets of raiseboring equipment in the world, Redpath leads the way in technology and experience. Technological advances, such as the introduction of volts per hertz drives to the industry, are now becoming a standard in the manufacture of raise drills. The capability of semi automated operation, additionally enhances our state-of-the-art raiseboring services.

REDBORE 30 The Redbore 30 was designed specifically for rapid boxhole development. It is the lightest, most compact drill in the blind hole, box hole market. The drill’s energy efficient power pack and operating console have been combined into one unit making

this 2 piece compact drill extremely mobile maximizing move efficiencies. Nominal capacities range from 49 ft. (15 m) in length up to 43” (1.1 m) diameter with a back height of 13 ft. 3” (4.04 m).

The Model BH-30 is a third generation instrument designed to rapidly locate pilot holes that have failed to intersect a drift or other accessible target area. The equipment consists of a rugged waterproof Transmitting Probe and a small battery powered signal strength Receiving Unit. When a drill hole fails to intersect the drift (or other open target area) the drill rods are removed and the BH-30 Transmitting Probe is activated

then lowered to target depth. The BH-30 Receiver may then be used to obtain the approximate distance and direction of the Probe by an operator walking within the target area and observing received signal strength. The BH-30 Transmitting Probe may be used with the BH-10 or BH-20 Receiver Unit. It is powered by 4 ‘C’ cells and is Crystal controlled at 990Hz. The BH-30 Receiver Unit is tuned to 990Hz and powered by two standard ‘9v’ batteries. A Solid-state columnar readout provides distance in feet from the Transmitting Probe.

Saves time and money by reducing probe hole drilling

THE REDPATH GROUP Established in 1962, Redpath provides full and comprehensive expertise and experienced services to the global mining industry. Companies choose Redpath for our global family of highly qualified personnel, unwavering commitment to maintaining the highest safety standards and our ability to meet deadlines. Technical and operational expertise contributes greatly to our reputation for practical and innovative performance, resulting in the successful completion of complex, challenging mine development and construction projects.

Project Highlights In the mountains of Irian Jaya, Indonesia, Redpath has worked continuously since 1981 and has excavated raises inside adits at an elevation of 4100 m (13,451 ft.). Initial access to the mine and raise drill sites was via the largest single span cable car tram in the world, or by helicopter. In the Arctic, Redpath raisebored the first raise in permafrost, and completed surface raises during February and March when temperatures plummeted below -40°C. Initial access to these projects for machinery, personnel and supplies was primarily by aircraft.
