Jobs threat under Aberpergwm Colliery closure plans
There are fears jobs could go under plans to mothball a coal mine in Neath Port Talbot.
A 30-day consultation on proposals for Aberpergwm Colliery, near Glynneath, is due to start on Friday, according to the National Union of Mineworkers South Wales branch.
American owners Walter Energy have been asked to comment.
The mine employs about 60 staff after 300 workers lost their jobs in 2012.
