Coal mining has played a significant role in the UK’s industrial history, and many areas remain affected by legacy mining operations. A Coal Mining Risk Assessment (CMRA) is essential for assessing risks such as subsidence, mine gas emissions, and unrecorded mine shafts before any development takes place.

Why is a CMRA Important in 2025?

With stricter planning requirements and an increasing focus on land stability, a CMRA is often required before planning permission is granted. The assessment identifies potential hazards and recommends mitigation strategies to ensure safe development.

Key Risks Identified in a CMRA
  • Ground instability due to historical mine workings, which could result in unexpected collapses.
  • Mine gas emissions, including methane and carbon dioxide, which pose health and safety risks.
  • Surface subsidence caused by old mine shafts and tunnels, potentially damaging structures.
  • Water ingress from abandoned mine workings, affecting foundation stability and drainage.
Who Needs a CMRA?

Developers, landowners, and planners must ensure that any proposed construction on former coal mining land is safe and meets regulatory standards. Without a proper CMRA, a project could face legal challenges, financial losses, or significant delays.
