Raise boring that’s on the move

Raise Boring, Whole of Mine

---

PYBAR has recognised raise boring as a complementary component of its underground service, with raise boring offering important advantages over conventional methods.

This new division includes a Redbore 50 MDUR (capable of box hole or conventional raise boring) and a fully mobile Redbore 40 with its own engineered and certified transporter.  Equipment is manned by an experienced team of 10 people.

The raise drill 40 transporter enables it to relocate independently throughout the mine, without interruption to mine equipment or operations. The unit is self-sufficient, just plug the transporter into mine power and the raise drill is ready to go, offering improved safety to the operator who controls the drill from inside the air-conditioned cab.

Capabilities include:

• Conventional raise boring from 724mm to 2.13m with lengths up to  182m
• Box hole/upreaming from 724mm – 1.52m with lengths up to 30
