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.
