Hydraulic coal mining - Seddonville | NZHistory, …

The earliest attempts at hydraulic mining involved transporting coal from the mine mouth to the nearest road or rail transport. For example, in 1924 a flume (water race used for carrying coal) was constructed from the mouth of the Cardiff Bridge mine to the railway at Seddonville, a distance of 1.6 km.

In the hydraulic mining of gold the rebounding stream of water and mineral fragments is directed into sluices in which the gold settles behind baffles but the lighter waste matter is washed away. In hydraulic mining of coal the water simply breaks the coal from the seam and washes it to a collecting point. See also placer mining.
