Raise borer BBM

The BBM technology was developed by Herrenknecht for the rapid and safe construction of vertical and inclined raises or shafts, so-called slot holes. It can be used in stable rock formations and enables drilling diameters of up to 1.5 meters with a maximum drilling length of 60 meters. In developing this technology, a particular focus was placed on improved occupational safety, higher productivity and an optimum mobility of the rig. The time-consuming preparation measures required for conventional methods are no longer necessary.
