The Durham coast
The second of the National Coal Board’s off-shore boring towers started work off the Durham coast in August, 1958, and it was recently announced that undersea coal reserves have been proved amounting to 300 million tons. Eight boreholes between 1,600 ft. and 2,600 ft. in depth were drilled, two off Blackhall and Horden, three off Sunderland, and three off South Shields, where the ninth hole is now in progress. Of 20 seams found, those from 2½ to 8 ft. in thickness are regarded as workable, and additional information will in due course be available from other boreholes to be drilled off Seaham and Easington.
