Gallery: Sirius Minerals’ polyhalite mine “progressing well”

Work to develop the Woodsmith mine site for the new polyhalite mine in North Yorkshire is progressing well, according to project develop Sirius Minerals.

The latest images of the work from Sirius show that diaphragm walling work on the service shaft has been completed and work is now underway on excavation.

Bauer Technologies has now started work on the diaphragm wall for the 36m diameter production shaft.

Work currently underway at the Woodsmith site includes preparations for the excavation of the first 120m of the mineral transport system (MTS) shaft using a Herrenknecht vertical shaft machine (VSM). DMC is expected to start sinking of the shaft using the VSM by the autumn.

At Teeside where the 37km long MTS tunnel will reach the surface, work is underway on piling for the tunnel portal and Strabag is expected to start tunnelling activities when the portal is sufficiently advanced. In addition to the portal construction, earthworks for support infrastructure such as power supply and welfare buildings is progressing at the Teeside site.
