I feel the need to include something on the subject of the
threat that disused mine workings pose to land and property owners. Its seems
that recently, our chickens are coming home to roost. The situation is
particularly bad in Cornwall. A few years ago, at Gunnislake, a major part of a
housing estate was evacuated after someone's garden disappeared down an old
shaft. Recently someone's drive on St Ives hill collapsed into an old shaft, you
could look down and see all the services exposed, what you couldn't see was the
bottom. In 2003 a collapse started on the Tesco supermarket car park at St Ives.
This was excavated into old mine workings.
