The Herrenknecht Reef Boring Machine (RBM) safely and efficiently creates horizontal and ascending boreholes with inclinations of up to 40°. In stable rock with up to 300 megapascals and with excavation diameters of up to 1.5 meters, the RBM achieves borehole lengths of up to 40 meters.
Herrenknecht has developed the RBM for the rapid and highly efficient mining of ore veins. The RBM technology optimizes material extraction by means of a pneumatic suction line directly behind the cutterhead. Compared to other mechanized methods or blasting, the procedure minimizes ore losses or contamination. The high boring
accuracy of the directionally steered drive also minimizes the excavation of adjacent rock and maximizes targeted ore extraction.
With its compact modular design the RBM is also ideal for use over very small distances and can be transported quickly from one boring location to the next. Time-consuming preparatory work, e.g. for a concrete pad or pining of the machine, is eliminated, increasing productivity. At the same time, work safety is improved thanks to the very high degree of mechanization and automation, since fewer people are in the danger zone.
