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 1.8 meters with a maximum drilling length of 70 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. • More about Boxhole Boring Machine: • https://www.herrenknecht.com/en/produ...
