Our specialist team of geologists and engineers at GRM have been helping landowners and developers understand and mitigate a wide range of mining related scenarios for over 30 years.
What is Involved in a Coal Mining Risk Assessment?
A CMRA is a desk-based study that researches the historical mining legacy of a site and provides a site-specific assessment of the risks that could affect future developments. This can include ground subsidence (from underground and surface mine workings), mine shaft entries, and mine gas.
We use historical ordinance survey maps, geological maps, mining records (memoirs/maps/plans) and over 30 years of experience to characterise the site and evaluate the level of risk to the proposed development. If the risk is deemed too high at that stage, further on-site ground investigations may be required such as boreholes which can help to confirm the level of risk.
All CMRAs should identify coal mining features present within a defined area and the risks these pose. The assessment should also set out any investigatory works and the remedial or mitigation measures needed. The CMRA must demonstrate to the local planning authority that the site is suitable for the proposed development and can be made safe and stable.
Why Choose GRM for your CMRA?
GRM has been helping landowners and developers understand and mitigate a wide range of mining related scenarios for over 30 years. On sites where past mining activity has been identified as a risk, our team of Chartered Geologists and Engineers can then advise on the most appropriate and cost-effective way to remove the risk to your site and render it suitable for the proposed end-use.
We have a dedicated team of professional geologists and engineers who have extensive experience supporting landowners and property developers with coal mining risk assessments. This includes providing advice and mitigation identified from the initial desk-based study or subsequent on-site ground investigations (should the need be identified).
Any risk assessment can get through planning if it recommends Probe Drilling, however, GRM prides itself on producing high quality risk assessments and we will not recommend Probe Drilling unless we believe it is absolutely necessary in order to quantify the risk. Probe drilling costs for a small site are likely to be more than 10 times the cost of a good CMRA and can result in significant disturbance and clean-up costs too.
Our teams have delivered CMRAs for a wide range of clients from individual domestic property owners through to large housing developers. In all cases we take pride in our professional and supportive approach, which typically leads to additional or repeat work with the client (over 80% of our work comes from existing clients who trust us and benefit from our proven track record of saving both time and cost).
