New Zealand coal reserves are in excess of 15 billion tonnes, mainly in Waikato, Taranaki, West Coast, Otago and Southland. [10] Over 80% of the reserves are in Southland lignite deposits worth $100 billion. [2] In 2008 coal was produced from four underground and 21 opencast mines.

See all results for this question RRxQOQdlv67f Coal is a rock that can burn, and it is made from carbon, water and minerals. It was formed millions of years ago when plants fell into peat swamps and were buried by heavy earth and rocks. Over a very long time, the weight of the rocks and heat in the ground turned the plants into coal. See full list on Most of the world’s coal was formed 300–350 million years ago. New Zealand coals are much younger – they were made 30–70 million years ago. See full list on There are different kinds of coal with varying properties that determine how it can be used. The kinds of plants that eventually turn into coal differ, as do the minerals in the coal. The most important factor is how deeply the original plant material is buried. It begins as peat and as it bes morepressed it gradually changes into lignite, See full list on There are coalfields in Northland, Waikato, Taranaki, the South Island’s West Coast, Otago and Southland. See full list on Europeans began mining coal in New Zealand in the 1840s. At first, men went underground and dug out the coal with picks and shovels. In the early 1900s men used explosives andpressed-air machines in mines to cut coal from the seam. The coal was loaded into wagons and taken out of the mine. From the 1990s high-pressure water jets were used to cu See full list on Underground mining was dangerous. Rocks fell, men were knocked over by the wagons carrying coal, there were explosions, and miners were suffocated by poisonous gases. An explosion at the Brunner mine in 1896 was New Zealand’s worst industrial accident, with 65 people killed by toxic gas. In the 2000s mining was generally safer because of government See full list on Many of the early miners came from Britain, where there was a tradition of trade unionism to improve miners’ working conditions. Many New Zealand mining towns became centres of strong union activity. Some of the union leaders later became members of parliament.
