VDMA 31 2019 • VDMA MINING SUPPLEMENT In addition to large shaft-sinking systems, Herrenknecht has mobile boring technology in its portfolio. A compact design is combined with innovative solutions and thus offers a high degree of flexibility. The Boxhole Boring Machine (BBM), for example, is based on the principle of proven, horizontal pipe-jacking technol- ogy and creates vertical and inclined shafts with small diameters in stable hard rock. BBMs as well as Boxhole Backreaming (BBR), Reef Boring Machines (RBM) and Raise Boring Rigs (RBR) work ef- ficiently and reliably even in the tightest of spaces and the hardest of rock — remote controlled, too, if the situation requires it. Their modular design makes them easy to transport and quickly mobiliz- able. Each machine is equipped for the specific project, including, for example, the individual assembly of the boring machine with the appropriate cutting tools. In the mechanized creation of underground mining infrastruc- tures, Herrenknecht sets the highest standards of health protection, work safety and quality. As a technical pioneer, the company will continue to develop new technologies together with contractors and clients to make the construction of underground infrastructure in mines even safer and more economically efficient. With experience from more than 4,100 projects, Herrenknecht is a technology and market leader in the area of mechanized tunneling technology. It is the only company to deliver cutting-edge tunnel bor- ing machines for all ground conditions and in all diameters — from 0.10 m to 19 m. BHP Billiton's Jansen potash project in Saskatchewan is an ex- ample of using the technology to sink two 1,000-m deep shafts. DMC Mining Services used two SBRs to sink the two shafts that measured 8 m and 11 m in diameter. Shaft sinking was completed at the end of 2018. The rock was excavated using the partial-face method, with a cutting drum located on a telescopic boom, adapted from VSM technology for SSMs, and conveyed through the SBR via an innovative pneumatic system. The roadheader is remote-controlled from the deck on the shaft-sinking platform, allowing safe working conditions. Mecha- nized shaft sinking aims to achieve higher efficiency, which is im- portant for the cost-effective extraction of deep deposits. One of the world's most powerful raise boring rig, the RBR900VF, is in operation at BHP Billiton's Olympic Dam mine in South Austra- lia. The RBR is employed for the construction of 730-m-deep ven- tilation shafts in hard rock. Thanks to its design, the remote-con- A shaft-sinking platform equipped with a Herrenknecht SBR is lowered in the shaft at BHP's Jansen project in Saskatchewan, Canada.
