Delabole Slate Quarry
Delabole Slate Quarry
This picture is from the days when there was no lake at the bottom, just an excavator and dumper truck. The slate has been quarried continuously since the early 17th century. The quarry is 425 feet deep and more than a mile and a half in circumference, and provides a quality of slate that is exceptional. In 1860, the quarry employed about 1,000 men, blasting and cutting about 120 tonnes of slate per day, which was hauled six miles to Port Gaverne to be loaded onto vessels moored in the harbour. It would take thirty wagons, pulled by over a hundred horses to load a sixty ton ship. Later the railway provided the transport. Today they only employ about five people in the actual quarry, still producing about 120 tonnes per day. There is no blasting and very little waste material. Vertical and horizontal holes are drilled to meet up, then a diamond wire saw is inserted to cut out a 600 tonne block.
