Coal Seam Levels for Underground Working Depth in the UK

A dataset from the Mining Remediation Authority shows the depth of underground coal workings in metres relative to sea level. Each record is associated with a specific point or contour and a specific coal seam. The data was last updated on 2026-04-14.

Use Cases

• Model ground subsidence risk based on recorded seam levels and working depths.
• Map historical mining activity extents based on contour and seam identifiers.
• Assess environmental remediation needs by correlating working depth with surface features.

Strengths

• Data is directly sourced from the authoritative Mining Remediation Authority.
• Depth values are clearly defined as being above or below Ordnance Datum/sea level.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to uk_data.
