We see an example of a Trepan Shearer and a voice over explains that it combines the large coal winning capacity of the trepan with the simplicity of the Anderton Shearer Loader. We then see the shearer in action cutting coal underground at Boldon Colliery (Tyne and Wear); Littleton Colliery in Staffordshire and Whitwick and Merry Lees Collieries in Leicestershire.
