unknown machine

[dazbt]

Bit of a mystery machine, can anyone identify this machine type and the manufacturer? Does anyone have details of its installation and how it performed. These particular photos were taken in Shilbottle pit yard I believe in 1964, I've seen a reference to a training course being given which I believe was on this same machine but can't find any further detail, anybody help?

Trepanners were a type of coal cutter that used a spinning auger which would cut into the coal like an apple corer, and turrets on the top or at the sides, to cut and peel large chunks away from the face.

They were also know as in seam miners. They were usually used in low high coal seams.

The coal face machine was a Double Ended Floor Mounted Trepanner that had seven cutting elements; a rotating drum at each end that trepanned the coal, an adjustable turret that cut the roof, two jibs that undercut the coal and floor and two side jibs that straightened up the face side of the seam. The “Trepanner” hauled its self in both directions on a haulage chain consisting what I believe was 18mm thick links.

It's not a trepanner, Daz was a Coal Board trained fitter, who spent many years working for Anderson Strathclyde installing and problem solving for them in the "field" at mines across the world, that's his little Grandaughter standing in the trepan wheel of a double ended conveyor mounted trepanner learning the ropes....LOL
