A selection of photos of these hard working ponies, used underground, often replacing child or female labour, as distances from pit head to coal face became greater. The first known recorded use in Britain was in the Durham coalfield in 1750.

At the peak in 1913, there were 70,000 ponies underground in Britain. In later years, mechanical haulage was quickly introduced on the main underground roads replacing the pony hauls and ponies tended to be confined to the shorter runs from coal face to main road (known in North East England as "putting") which were more difficult to mechanise. As of 1984, 55 ponies were still at use with the National Coal Board in Britain, chiefly at the modern pit in Ellington, Northumberland. Probably the last colliery horse to work underground in a British coal mine, 'Robbie', was retired from Pant y Gasseg, near Pontypool, in May 1999.
