Top tips: Coal mining risk

Legacy coal mining structures can represent a significant and often unanticipated development constraint. The presence of coal mining legacy structures requires consideration when defining your development layout and will lead to abnormal development costs associated with capping of mine shafts, grouting of mine seams, deepened foundations and extended programmes. Early consideration of coal mining legacy structures is key to the successful delivery of a development in former coal mining areas. Check out our top tips below on how to manage and mitigate these risks to meet and enhance your project deliverables.

✔ Top tips

  • Check if your development is within a Development High Risk Area
  • Complete a Coal Mining Risk Assessment (CMRA) early in the design process
  • Consider your layout and the potential to avoid development in high risk areas of a site (mine shafts, adits etc)
  • Consider the impact of coal mining legacy structures on foundations and structures
  • Engage all of the relevant stakeholders
  • Seek specialist advice on the likely influence of coal mining legacy structures on the built development - remember the responsibility for a safe development resides with the developer

× Things to avoid

  • Do not ignore coal mining risk - your planning application will not be validated where your site is within a Development High Risk Area
  • Do not locate development over shafts or adits where this can be avoided
  • Do not ignore the impact of coal mining - there are 1,000 insurance subsidence claims a year relating to coal mining
