  • Coal Outcrops - Dataset showing known locations where a coal seam is near the surface.
  • Development High Risk Area - Dataset showing part of the coal mining reporting area which contains recorded coal mining related features.
  • Fissures and Breaklines - Dataset showing types of geological disturbances which may have been affected by coal mining.
  • Mine Entry - Dataset showing known mine entries indicating the entrance into a mine working.
  • Mine Entry Potential Zone of Influence - Dataset showing the area of the ground that might be affected if subsidence a mine entry occurs.
  • Past Shallow Coal Mine Workings - Dataset showing underground coal workings whose depth is 30 metres or less from the surface.
  • Probable Shallow Coal Mine Workings - Dataset showing likely extent of shallow underground coal workings for which no recorded plans exist.Surface Mining (Past and Current) - Dataset showing areas of coal extracted by surface excavations in the past or currently being excavated

Technical Blurb

These layers are streamed directly from The Coal Authority so if the loading of the data is slow or broken then please let us know but please don't blame us!

The data is 'zoom restricted' so some of the layers will disappear if you zoom too far out, or too far in. This means you won't be able to zoom into property level. The reason for this is the data isn't that accurate and The Coal Authority don't want you misinterpreting it.

If you need more detailed information then we can put you in touch with 'coal professionals' at The Coal Authority who will be able to help.
