Trial Trenches Expose Historical Coal Mining Entries near Bristol

A combination of trial pitting and trenching was undertaken at a site in an area of historical coal mining to the north of Bristol as part of a coal mining risk assessment. This exploratory technique was used to provide an indication of the natural ground conditions beneath the site, as well as to delineate historical mining features, including mine entries.

The trial trenches and trial pits enabled a sufficient volume of the ground to be inspected and historical mining features to be identified and described by our engineering geologist, whilst maintaining a sufficiently safe distance from the historical mine entries.
