PLANNING CONTEXT
Why might you need a CMRA?
Historic coal mining can create ground stability risks. A Coal Mining Risk Assessment identifies and evaluates mining-related features so that their implications for a proposed development can be understood.
For most forms of development in a Development High Risk Area, a CMRA must be submitted to the local planning authority. Some exemptions apply. These areas contain recorded mining features that may pose risks to surface stability.
The Mining Remediation Authority, formerly the Coal Authority, provides planning advice on coal mining legacy risks. Read the official planning and CMRA guidance.
ASSESSMENT CONTENTS
What the assessment includes
We bring together mining and geological information to identify credible risks and explain the next steps for the site.
- A consultants’ mining report from the relevant mining authority.
- A review of BGS geological maps at 1:50,000 scale.
- A review of larger-scale geological maps, including 1:10,000 or six-inch-to-one-mile mapping.
- A review of BGS borehole section sheets.
- Identification and qualitative assessment of coal mining risks.
- Evaluation of credible risks and proposals for mitigation or further works.
FURTHER INVESTIGATION
What happens if a risk is identified?
Where the assessment identifies potential risks that need further investigation, a site investigation may be required. Its scope is agreed with the relevant authority before works commence.
Further investigation may be secured through a condition attached to the planning decision. The timing and scope must follow the requirements for the particular development.
Our geotechnical investigation services include rotary drilling techniques that can help investigate shallow coal seams and mine workings.
