90 meter-deep sinkhole opened up in Terrace House Residents

sized gaping sinkhole in the backyard of a house in the suburbs Scorrier, Cornwall, England which has a mining history. The collapsed hole is estimated to have a depth of up to 90 meters or more.

As reported by News.com.au, cave-like hole was found experts while looking for traces of mining through an old map at that location. Luckily, the house was empty when the ground suddenly collapsed.

"The hole was huge. Its depth is roughly about 91 meters of water at the bottom of the hole. I do not know, how in again from there," said Mark Thomas, who explored the hole with unmanned aircraft (drone).

Since researchers began drilling exploration holes, almost half of the garage and the home page disappear into the Earth.

"No one knows that it is a mining corridor. Liang was open when scientists drilled under the porch of the house," said Stuart Eye Dann from the mining company.

"If you go back to 1750, the area was completely different. The area there are dozens of home machines, air filter and hundreds hallway mine, this area used to look like a desert," said Stuart.

In addition, Stuart also provides an explanation of the circumstances surrounding the mining area is currently closed.

"When the mines closed, large logs close the hole and bury them with soil. I think when it is the safest way. And over time the presence of machinery and mining hallways were closed as if he was never there," said Stuart.

But that apart from old maps that have detailed explanations related to the location of the mining area and the presence of the mining corridor.

Old map that's become home purchases difference that stands firmly on the ground or hallway mine.

"Liang will remain open as long as the investigation is done. The refinery drilling will be used to check for vacancies ground to the bottom hole," said Stuart.

"The expert design and construction will now decide the future of the building. However, cracks in buildings gives speculation that the house unfit for occupancy."
