| Colliery Overview |
Collieries can be divided into three areas – the pit head, pit yard and underground workings. From the surface of a deep mine the most prominent feature is its pit head. The pit yard consisted of all the surface buildings necessary for the running of the mine. The underground workings are the largest part of the mine, sometimes miles long, where the coal is extracted from.
