300ft mineshaft opens up in Cornwall garden

The deadly drop opened up in the back garden of an unoccupied bungalow while it was being surveyed.
Estimated to be at least 300ft deep, the huge hole was once part of an 18th century tin mine and opened up unexpectedly while surveyors were checking the property for ground stability.

"There was nothing there at all that shows there was a shaft," said Stuart Dann of Mining Eye.

"Both houses nearby are empty, which is a very good job. It is easy to see the woods, fields and houses and assume nothing was there. If you go back to 1750, the area was completely different."

Local man Mark Thomas, who managed to capture some impressive aerial video footage of the mineshaft using a remote-controlled drone (below), described the hole as "truly massive."

"Itís approximately 300 feet to water and god knows how deep from there," he said.

The original surveyors and builders probably have been dead for decades.

The original surveyors and builders probably have been dead for decades. Looks like no one is going to get sued, the properties were unoccupied and the "experts" would not have been permission to drill if there had been occupants. I missed this bit. Cornwall is full of abandoned mines and this one was discovered when local experts set out to look for more holes after looking at age old maps. Stuart Dann, from Mining Eye, said that the discovery was unexpected. He said: ĒThere was nothing there at all that shows there was a shaft. The shaft opened up when experts were drilling down the patio. h... [More]

The original surveyors and builders probably have been dead for decades. Unfortunately, a couple of them might be down that shaft.

Wouldn't there be tunnels off the shaft if it was a mine?

Wouldn't there be tunnels off the shaft if it was a mine? Yes, but they could be below the water level. One of the first uses for Boulton & Watt's steam engines was to pump water out of Cornish tin and copper mines

Sinkholes- there's some freaky sh|t right there. Like that guy in Florida whom went down in a sinkhole while sleeping in his own bed. That incident was just surreal. In his bed, in his room, in his house, in the middle of the night, a sinkhole opens up just in his particular bedroom, and leaves the rest of the house untouched. Makes you think there is a higher, or lower, power at works here. His brother, and mother I think it was, awoke in their respective bedrooms, in the same house, hearing him screaming bloody murder , and his brother runs and open his bedroom door and his brother, his, bed...

I lived in Gympie, Australia which was a major gold mining town from about 1865 until 1915 or so. Legend had it that all the mines has connected up underground and you could walk from one end of the town to the other, which would have been close to 3 kilometres. Some mine openings were near the river and flooding ran water into them, which promptly filled all the mines. After the second time this happened, the miners gave up. After heavy rain holes appeared here and there. One appeared in the middle of the outdoor basketball court of the high school about 200 metres from home, and a neighbour ... [More]
