It got its name from the large elliptical shaft, which was wide enough to accommodate two coal trams side by side. It was approximately 39 metres deep in 1860, but was deepened in 1880 to nearly 90 metres.Image caption, Prior to the introduction of the pithead baths in 1939, miners travelled to and from the mine in their working clothes.
