He drives at about 20 miles an hour down the size of the man-made canyon, about 150 ft throughout, its sides striated in browns and tans and grays, to the spot the place the dragline is working. That’s a good greater piece of kit (it weighs 4,500 tons and appears like an old school steam shovel blown as much as 40 occasions its regular measurement), scooping up soil in an enormous bucket and exposing the seam of coal.
