Disused Coal Tips in Wales Map

This dataset was last updated in May 2025.

This dataset shows the locations and boundaries of disused coal tips in Wales. This includes disused tips of ALL categories (categories D ,C, B, A, and R).

This dataset includes an attribute that shows the Unique IDentifier for each tip [UID], its category rating [Category], the Local Authority it is located in [Authority], and the last date each disused coal tip has been last inspected [Last Inspected] on behalf of the Welsh Government by the Mining Remediation Authority (MRA).

This data will be refreshed twice annually (once in the spring and once in the autumn) to align with the continuing programme of inspections for category C and D disused tips.

This dataset is part of a programme of work to review and improve coal tip safety in Wales being delivered by Welsh Government and its partners.
