The dataset comprises plans of various types relating to mining activity, including abandonment plans, gathered since the 1800s. Most were collected as part of the BGS mapping programme and the type and amount of data available will vary considerably by area. The coverage for Northern England and Scotland is more comprehensive than for the rest of the country. The plans include working copies, compilations and interpretations which may be copyright or confidential. The BGS mine plans are indexed in the BGS mine plan database along with metadata and scans of mine plans held on behalf of the Mining Remediation Authority (MRA) and the Health and Safety Executive (HSE) for online delivery. The general nature of some of the plans means that they may not be applicable to a specific site. Current holdings over 80,000.
