The hinged chutes, which are lowered to drop ore from the pockets into ships, are located at twelve-foot intervals over the length of the dock. This spacing is not coincidental, as the docks and the lakers they could load evolved together, and laker hatch spacing is typically 12, or 24-foot (7.3 m) on center.

For comparison, the uranium mined at McArthur River uranium mine, the largest uranium mine in the world, would be equivalent (at a CANDU-typical burnup of 200 MWh/kg) to 4.46 exajoules (1.24 × 10 12 kWh) of thermal energy, but used for the more common types of nuclear reactors, the uranium mine produces less energy content than North Antelope ...
Early logging flumes were square wooden chutes known as box flumes. These were prone to jams that could cause damage and required constant maintenance. They were also costly to build. A square box carries much more water compared to a V-shaped flume. The greater weight of the water required a sturdier structure, especially heavier trestles.
