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.

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.
