Overview

A small private drift mine on Varteg Hill above Varteg, worked from 1992 to 1997, whose corrugated adit shed and loading gear still stand.

History

Cwm Glo Colliery, also called Cwm-y-Glo, was a small drift mine on Varteg Hill above Varteg, near Pontypool, lying in a dip just beyond the head of the old Varteg Incline and close to Varteg Hill Colliery. It was opened in the 1990s and worked for about five years, from 1992 to 1997.

Its surface works were small. At the top a blockwork winding house held a winding drum with a steel rope, and a tunnel of corrugated iron carrying two tramways led down to the drift entrance. There were screens, a loading dock and a safety brake, and a haulage engine and compressor building. An access road on an embankment three metres high ran north for about 150 metres to the trackbed of the former LNWR Varteg Hill Colliery branch, which served the mine as its track to the B4248.

Geology

The South Wales coalfield on Varteg Hill.

Workings

A drift reached through a corrugated-iron tunnel carrying two tramways, hauled by a winding drum and steel rope from a blockwork winding house; screens and a loading dock at the surface.

Closure

Worked for about five years and closed in 1997; the drift entrance is blocked with spoil.

What remains

The drift entrance is blocked with spoil. The haulage engine and compressor building stood until 2008 and has gone; the green corrugated adit shed, screens, loading dock, rails and safety brake remain, and the site is slowly being stripped.
