Crawler chassis mounted intelligent 3m raise borer from 60 to 90 degree

A raise borer is a machine used in underground mining, to excavate a circular hole between two levels of a mine without the use of explosives.

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.
