3.5m raise diameter 400m depth raise boring machine raise borer
The raise borer is set up on the upper level of the two levels to be connected, on an evenly laid platform (typically a concrete pad). A small-diameter hole (pilot hole) is drilled to the level required.
Design inspiration
Our professional team consider the mining technology requirements
and absorb the advanced design concept in similar products.
STD-R120 raise boring machine came into being. It is based on our
technology advantages, professional manufacturer, advanced
processing technology and rich producing experience.
