Sinking a mineshaft by Triger's method (1841) devised for use in the difficult conditions of the Basse-Loire coalfield, France. Cast iron cylinders sunk to riverbed. Worker at bottom is in a virtual diving bell into which compressed air is being pumped. The compressed air holds back most of the water that would otherwise filter through the sands.
