HC Deb 14 July 1958 vol 591 c68W
59. Mr. T. Brown

asked the Paymaster-General what general directions he has given to the National Coal Board with regard to the avoidance of damage in the neighbourhood of opencast coal operations and particularly with regard to the weight of explosive used.

Mr. Maudling

None. But in authorising the National Coal Board to work opencast coal on sites requisitioned under the Defence Regulations my noble Friend imposes conditions in appropriate cases to minimise damage from blasting. These conditions vary from site to site.
