Hydraulic Mining Of Coal

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.

Hydraulic Coal Mining Article about Hydraulic Coal

Hydraulic Coal Mining the underground working of coal deposits in which the coal is excavated, transported, and lifted to the surface by using the energy of a water jet. The source is usually underground water flowing into the mine.

hydraulic mining, use of a powerful jet of water to dislodge minerals present in unconsolidated material, including mine tailings, placer deposits, alluvium, laterites (soil rich in iron oxides), and saprolites (soil rich in clay). It has also been applied to consolidated materials from sandstones through coal to hard rock.

Hydraulic Coal Mining Article about Hydraulic Coal

In hydraulic coal mining the coal bed is broken down either by means of a high-pressure water jet (5 to 10 meganewtons per sq m), which is formed by monitors, or by means of mechanohydraulic machines (mechanical breakdown of the coal with subsequent washing out by the water). The water is supplied to a stope through pipes from centrifugal pumps.

The method of mining coal entails the use of crude petroleum under high pressure together with elevated temperatures in hydraulic fashion to produce a hybrid oil-coal fuel. A powerful stream of oil is aimed at sections of coal strata to disintegrate the coal.

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

Hydraulic borehole mining for pitching coal seams. Final

The borehole hydraulic coal mining system accesses the coal seam through a hole drilled in the overburden. The mining device is lowered through the hole into the coal seam where it fragments the coal with high-pressure water jets. The fragmented coal is pumped to the surface as a slurry by a jet pump located in the center of the mining device.
