South Africa is one of the ten largest coal producers and the fourth largest coal exporting country in the world. As the coal seams here are buried too deep beneath the ground for opencast mining, they are deep mined using a room and pillar technique.
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 hose mining industry. Hydraulic Mining - CPRR Photographic History Museum, was the first to use a large hose in ground-sluicing, and that in 1853 Edward E Mattson of American Hill near Nevada City first used a metal nozzle at the end of a hose to wash down a .
Hydraulic hose are used in a number of industries including coal mining, tunnel building, petroleum related processes and welding. They allow liquids to be able to transfer at very high pressure safely and securely in hazardous environments. Hose are made from high quality rubber and are heavily insulated which increases their durability whilst being able to direct fluids in at consistent ...

Each mine site's culture dictates what is used, e.g. abrasion sleeves on the hose or extra-tough covers. Most hoses used at a surface operation are hydraulic in nature. But many industrial hoses are also used in shops and at the mining sites for air, water, nitrogen charging, drilling air, petroleum and water.

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.
The chocks were interconnected with hydraulic hoses and connected back to a pumping arrangement in the gate road by a hydraulic fluid reticulation system. The hydraulic fluid used was (and still is) mostly water with a low concentration of soluble oil, partly to assist in lubrication but mostly to inhibit corrosion.
SteckO staple hydraulic hose connectors are the preferred choice used in longwall coal mining operations worldwide. Super SteckO is a high performance staple adaptor. It was introduced to increase essential performance and safety standards to match the advancement of coal mining technology.
The total enclosure of hydraulic systems in, for example, a cast steel machine casing, so that they are inaccessible to sources of ignition and it is unlikely that fluid will spray into the surrounding atmosphere, has been found to give a safe situation for the use of mineral oil hydraulic fluids in UK coal mines.
