Woolmet Colliery, near Danderhall, was owned by the Niddrie and Benhar Coal Company.
It had one shaft (735 feet) and one surface mine supplying mainly house coal. It was one of the first collieries to adopt air blasting rather than shot firing.
This photograph shows the newly electrified winding engine that operated the deep mine shaft at the colliery.
One of the first electric winding engines in Britain was installed at Harton Colliery, Tyne and Wear in 1908. Their general introduction, however, was gradual, many companies continuing to use steam winders up until the 1960s. Photo: National Mining Museum Scotland/Scran
