Hydraulic mining Wikipedia
Hydraulic mining is a form of mining that uses high-pressure jets of water to dislodge rock material or move sediment. In the placer mining of gold or tin, the resulting water-sediment slurry is directed through sluice boxes to remove the gold. It is also used in mining kaolin and coal.. Hydraulic mining developed from ancient Roman techniques that used water to excavate soft underground deposits.

Hydraulic coal mining Seddonville NZHistory, New
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. It was soon discovered that wood was rapidly worn away, so the flume was lined with iron
