Marchienne coal mine taken over by Belgian company in 1908; shaft 16 1/2 ft. diam. sunk to 4200 ft.; most of coal is taken from level at 3770 ft.; greatest difficulty is to keep roadways open, on account of pressure; rock-temperature data; ventilation; care required in choosing men physically and mentally adapted for working at depth. (Abstract translation) (See also Revue Universelle des Mines vol. 73, no. 1, May 1931 pp. 250-255)
