A 300ft-deep mine shaft has opened up under the patio of a Cornwall house: http://www.bbc.co.uk/news/uk-england-35800866

So the surveyors made it fall in?
Yes Roger, I'm sure that's what the report I read meant to say! Otherwise it'd require rather a lot.Roger W said:It says they are going to "re-cap" it, Tony. That should take a bit less concrete than filling the whole hole.
have to be a proper job with concrete from where the ground is good, and ensures you always know the state of the shaft - better than capping it or fillinf it and wondering if the fill is settling!Roger W said:The danger is that you might end up with bedroom, living room, kitchen and bathroom down the shaft...
