Aberpergwm is the site of a colliery in the Vale of Neath near Glynneath in south Wales.
The drift mine was reopened in 1996 after being closed by British Coal in 1985. It is owned and worked by Energybuild, a private company now wholly owned by Walter Energy of the USA (as of April 2011). The mine has probable recoverable reserves of 7.6 million tonnes of coal.[1], which is a high-grade anthracite. Most is delivered to the Aberthaw power station to the south of Cardiff.
The ruined, derelict Aberpergwm House stands on the grounds, the former seat of the Williams family of Aberpergwm.
