Mine

Sirius Minerals Plc. has hired the European construction group Strabag to build a 13 km tunnel section for the underground transport system for the Woodsmith Mine near Whitby, England. The design-and-build contract was signed on 28 March. The Woodsmith Mine will begin extraction from the world’s largest deposit of polyhalite, a mineral used in the production of fertilizer, in 2021.

The section to be built by STRABAG is part of a 37 km tunnel with a diameter of 4.7 m for an environmentally friendly conveyor system to transport the mined polyhalite to Wilton for processing. The Strabag contract also includes the construction of a tunnel ramp as well as the tunnel portal at Wilton. The actual tunnelling works will cover the distance from the Wilton portal to a shaft at Lockwood Beck, with 150 m to be built via cut-and-cover construction, 800 m through conventional tunnelling and 11,900 m using a tunnel boring machine. Site mobilisation is to begin immediately.  Visit http://www.strabag.com. 13/18.
