Raise Boring process progress

See general description of the RB method available in the public domain.How has the raise boring technique evolved in recent years? Have there been any recent significant technological advances?

The basic concept is still the same, although the application of the method for various different excavations has evolved with success. The method is more know and excepted as a reliable tool for engineers. Also as mining requirements grew, the accesses to more personal are required and projects are more remote. Its popularity grows.

Drill rod metallurgical changes, cutting consumable quality and the control of the cutting process has significantly attributed to technology changes over the last few years.

How does the cutting technology vary for different rock conditions?

It is very important to understand the geotechnical characteristics and consistency of the rock formation to be drilled through. There are different parameters with regards to the different rock formations and is important to know where the geological consistency changes regarding the brittleness, toughness and abrasiveness to reduce operational risk and costs.

What would be best practice techniques for raise boring? How important is good operator training?

Operating training is off high importance due to the potential risk of dropping a reamer head or gets a drill rod stuck during the drilling process. These risks can be mitigated and managed through proper training and replacing operator control for critical tasks by automated functions.
