It was situated on the Denby Grange estate owned by the Lister Kaye family, and was worked from the 18th century until 1985.
The colliery was on the Denby Grange Estate, home of the Lister Kayes, in an area where coal had been mined for many years.
Some coal was supplied locally, but much more was sent to distant markets to the east of Pontefract via the Calder and Hebble Navigation.
Milnes' pits were linked to the Calder and Hebble Navigation at Horbury Bridge by a wooden wagonway which was later laid with iron rails.
[6] Caphouse Colliery was again developed in 1876 when the steam winding engine house, boiler yard, chimney, stone heapstead and ventilation shaft were completed for Emma Lister Kay, the sole proprietor.
[5] Sir John Lister Lister-Kaye (1801-1871) linked Hope Pit, Caphouse, and Victoria Pits at Netherton to the Lancashire and Yorkshire Railway's Barnsley branch and the Calder and Hebble Navigation at Calder Grove by a private mineral line.
[14] The Prince of Wales Pit (subsequently named Denby Grange Colliery) was sunk close to the line near New Hall Wood in 1870.
[15] The mineral railway fell out of use apart from the end section when road transport was favoured over rail in the late 1940s.
