Over the weekend of 9th – 10th January there was a sudden outflow of water from the mine at Lea Bailey. At approximately 9pm on the Saturday local residents reported a loud noise heard from the direction of the mine, and on the Sunday morning debris and water were reported on the road below the mine.
On visiting the mine later that morning it was found that the mine doors had burst open, some rolling stock stored just inside the mine had floated out, and much of the mine site was covered in silt from the mine. Water was still flowing in abnormal quantities. Fortunately no one had been present at the mine when the doors had burst open.
By the following Wednesday the flow from the mine had returned to a more normal level. Damage to one mine door has been repaired and the mine site made safe. No railway equipment was lost or damaged by the outflow.
