HC Deb 27 January 1982 vol 16 c378W
Mr. Skeet

asked the Secretary of State for the Environment what he estimates it would cost to fence disused mineshafts and quarries on land in England and Wales for which the Government have responsibility so that the excavations constitue less of a hazard to people in the vicinity; and what acreage of land is involved.

Mr. Giles Shaw

Information on the number and extent of disused mineshafts and quarries on Government land is not held centrally, and I regret that no estimate can therefore be made of the cost of fencing.
