Tunnel Boring Machines For Whitby Potash To Be Shipped Over

Published by the Yorkshire Coast Radio News Team at 10:41am 23rd January 2019.

Machines to drill a tunnel between Whitby and Teesside for the Sirius Minerals Potash Mine are being shipped over from Germany.

Sirius has unveiled the first of its 1800 tonne tunnel boring machines that will construct the tunnel which will transport the polyhilate underground.

The 225-metre-long machine is undergoing final checks in Germany before being shipped to Teesside in the coming weeks, where it will be reassembled and start tunnelling in the second quarter of the year.

The machine will bore the first of three planned tunnel drives which will make up the 23 mile tunnel from a new underground mine, near Whitby, to a processing facility on Wilton International in Redcar. 

Two other machines are planned to be launched in 2020 from Whitby and Lockwood Beck, near Guisborough, to complete the final 15 miles of the six-metre diameter tunnel. 

Workers will operate the TBM 24 hours a day, 7 days a week, lining the tunnel with concrete segments as it goes.

When complete, the tunnel will transport up to 20 million tonnes a year of polyhalite ore on a conveyor belt from the mine, to a purpose-built processing and shipping facility in the shadows of the old Redcar Steelworks, for distribution around the world.

A tunnel was chosen as the transport solution to avoid impacting the local landscape and will have no impact on the ground above, sitting at an average of 250-metres below ground level.

Chris Fraser, Managing Director and CEO of Sirius said:

“The assembly of our first tunnel boring machine represents an exciting milestone for the company and the region. 

With over 1,000 people currently employed across all of our sites, the team working to make this project a success continues to grow as we deliver this world class project. 

We expect to create hundreds more skilled construction roles in the coming months to help build our mineshafts, tunnel and mineral handling facility.”

Sirius expect to reach the polyhalite seam in 2021 and to be producing 10 million tonnes of fertiliser per annum by 2024, bringing about around 1,000 new long-term operational jobs.
