Coal Outcrops with 50m Buffer from the Coal Authority

Coal outcrops illustrate locations where a workable coal seam is present at or close to the surface. This layer identifies where an underground coal seam reaches rockhead, indicating coal that may have been worked in the past. The dataset contains a 50-meter buffer on the dip side of the outcrops position as held by the Coal Authority.

Use Cases

• Identify potential shallow underground coal workings based on outcrop location.
• Assess land for historical mining hazards based on the presence of workable coal seams.
• Support geological mapping and resource estimation based on seam outcrop data.
• Plan construction or development projects by identifying areas of probable shallow subsurface activity.

Strengths

• Data is sourced from the authoritative Coal Authority.
• Includes a defined 50-meter buffer on the dip side of outcrops.
• Specifically identifies locations where coal seams reach the surface (rockhead).

Limitations

• Row count, file formats, and column-level documentation are unknown.
• Last update date is unknown; freshness unverified.
• May include areas with un-viable coal seams, not just historical workings.
