What is it?
The Mine Entry Report (MER) is a follow-up report to the Groundsure CON29M Official Coal Mining Search. Where mine entries (shafts or adits) are identified within 20m of a property, the CON29M recommends that they are investigated further through this interpretive (as opposed to automated) report.
What does it do?
The MER gives a clear statement on the risk presented by mine entries that have been identified in the vicinity of the property – this is provided by an experienced and qualified consultant from Mining Searches UK.
How is the zone of influence calculated?
Many factors that can influence the extent to which a mine entry impacts the area around it. This impacted area is known as the ‘zone of influence’. Through investigation using a variety of data sources, expert geologists are able to calculate the zone of influence and assess the specific risk presented by each mine entry. Inputs into this assessment include:
- Coal Authority mine entries data (c.175,000 records)
- Authoritative BGS geology data
- OS MasterMap property extents
- Underground roadway extents from the Coal Authority
- Knowledge and expertise from mining experts
What does the report include?
- A clear statement of risk associated with mine entries within 20m of the property
- Further details provided on each mine entry
- The calculated zone of influence for each mine entry
- Where appropriate connecting underground roadways are included
- An OS MasterMap site plan displaying the zone of influence of each mine entry
- Guidance on next steps in the event of subsidence damage
The price of the report depends on the site size, outlined below:
