1.2 Description

1.3 Abstract

The Abandoned Mines Catalogue is used as a search tool to determine the relevant abandonment plans to a given search criteria. The collection contains coal and other mineral abandonment plans, covering both surface and deep mining operations, which depict areas of coal and other mineral extraction and the point of entry into these workings. These plans being referenced by graticule squares based on the old County Series Plans.

1.4 Purpose

To identify the spatial location and coverage of abandoned mine plans.

1.5 Supplementary Information

The Abandoned Mines Catalogue was established in the early 1920’s to catalogue the plans of abandoned mines deposited under the 1872 Coal Mines Regulation Act and Metalliferous Mines Regulation Act. The need to establish a catalogue came about after two accidents, one in Stirlingshire in September 1923, resulting in the death of 40 workers, and one in Northumberland in March 1925, when thirty eight people were killed, both as a consequence of an inrush of water from old workings. As a result in July 1925 the Secretary for Mines made a widespread appeal for plans of old workings not covered by the statutory requirements or for the supply of information where it was not desired to give up the plans. The appeal was widely respond to and particulars of such plans were included in a new Cataloguing system that was published in five volumes between 1928 and 1931.

The catalogues were issued in the then Counties and were based on the established County Series mapping. A County Sheet covers a geographical area of 6 miles x 4 miles and these were deemed to be too big for basing the cataloguing system on. Therefore the system was based on quarter sheets (3 miles x 2 miles), with each quarter sheet being further split into graticule squares of 0.25 miles x 0.25 miles. These squares were then numbered 1-12 in an East/West direction and lettered A-H in North/South direction. Plans are then referenced by recording all squares in which workings fall.

The Coal Authority holds and maintains the Abandoned Mines Catalogue under an agreement the Health & Safety Executive.

This data has been derived from current information available to the Coal Authority. This information is updated on a regular basis and therefore is only correct on the date stated.
