1. Description

1.1 Keywords

Coal, Mining, Underground, Mining Report, Ground Stability, Surface Coal Mining

1.2 Abstract

Surface Mining Areas denote an area of coal extracted by surface excavations in the past or are being excavated currently, these sites do not necessarily reflect the extent of the excavation. Coal resources may still be available within these areas due to the inefficiencies of some historic mining techniques. These areas are often referred to as “opencast mining”.

1.3 Purpose

Together with the Surface Coal Resource Area data, provide information to Mineral Planning Authorities for assisting in defining Mineral Safeguarding Areas in policy strategy.

1.4 Supplementary Information

The National Coal Mining Database, which is based on the records held at The Coal Authority offices in Mansfield, Nottinghamshire, is updated on a regular basis. This dataset has been extracted from this dynamic database on the date stated below and therefore represents a snapshot in time.
