Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine a pit, and theHydraulic mining Coal and coal mining Te Ara,This diagram shows how water is effectively used in hydraulic mining. Safety considerations and the drive to obtain as much coal as possible from an area led to the progressive replacement of underground mining by opencast mines. However, underground mining was also revolutionised in New Zealand
Although hydraulic mining is sometimes used to mine coal underground, its primary application is on the surface, where it is a practical way to mine relatively fine-grained, unconsolidated material from placers, tailings, alluvium, and lateritic deposits. A major application is 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.
