Forerunner of Progress in
Mining, Quarrying, Construction
A double-track tunnel, 3,300 ft. long, 31 ft. wide, and 28 ft. high, lined with steel and concrete, is being driven under a West Virginia hill 2 miles east of Clarksburg, for use by the Baltimore and Ohio Railroad on its main line to St.
Louis. It will replace an existing single-track tunnel that was completed and put into service by the B&O in 1855.
The construction of the new tunnel is proceeding through shale and a 9-ft.-thick seam of Pittsburgh coal.
The coal bed had been mined previously by the room-and-pillar system, and some difficulty is experienced in controlling the roof and floor of the seam.
A description of the activities on the project is presented in an article on page 103, by C. J. Burton.
