The tiny village of Jansen and the largest potash deposits on earth are located in Saskatchewan, Canada.
The Australian mining company BHP Billiton Ltd. expects to mine up to eight million tons of potash ore annually in Jansen. The shafts are frozen up to 700 m depth for excavation through the Blairmore layer. The mine will be equipped with the most innovative mining technologies.
DMC Mining Services is currently sinking deep vertical shafts in soft medium rock with depths of up to 1,000 meters and with diameters of 8 to 11 meters with two Herrenknecht Shaft Boring Roadheaders (SBR). The rock is excavated using the partial-face method, with a cutting drum located on a telescopic boom, adapted from the proven Herrenknecht VSM technology for Shaft Sinking Machines, and conveyed via an innovative pneumatic system.
The roadheader is remote-controlled from the work decks, allowing safer working conditions. The Mechanized shaft sinking aims to achieve higher efficiency which is important for the cost-effective exploitation of raw material deposits. This system has proven flexibility and adaptation to special requirements of the project. In August 2018, the sinking of the two shafts was completed successfully.
