Intégrale are frequently asked to complete pre-development Coal Mining Risk Assessments and Coal Authority compliant Ground Investigations. Whilst the history of British coal mining is well known, Britain also has a rich heritage in mining many different minerals and ores.
One recent example involved the collapse of an old and long forgotten shaft within a garden in a village in the Mendips, Somerset. Here, old mining resulted in discrete shafts being sunk to access the calamine/zinc/lead ore below. Just look at the pock-marked surface from a 1946 RAF aerial image; each ‘crater’ is an individual shaft, sometimes taken as deep as 20m!
Here at Intégrale we pride ourselves on understanding the ground conditions. This allows our clients to develop the most appropriate technical and cost-effective solution.
