Mine fill failure causes Buckinghamshire collapse

A ground collapse that swallowed a car in a Buckinghamshire village yesterday is reported to have been the location of a previous mine collapse.

GE has learned from a local resident that a historic flint mine at the same site in Walters Ash caused a similar collapse 15 years ago.

It has been suggested that recent heavy rain has caused the backfill material placed in the original collapsed ground to subside and that the mine workings are more extensive than recorded during the investigation of the original incident.

The collapse has opened up a void 4.5m across and 9m deep below where a car was parked but the collapse has not affected the car owner’s property.
