The types of coal found in New Zealand include lignites, sub-bituminous, bituminous and semi-anthracite coals. [3] However, the geology of many coal fields can be complex, with significant structural tectonic disturbances caused by many fields being found near the boundaries between the Pacific and Indo-Australian tectonic plates that run through the country.

New Zealand Coal Production, 1878 - 2014. [10] Coal mining produced almost 4 million tonnes of coal in 2014, of which 44% was exported. [10] In 2016 it was down to 2,834,956 tonnes, [11] very similar to production in 2020. [12] New Zealand coal reserves are in excess of 15 billion tonnes, mainly in Waikato, Taranaki, West Coast, Otago and ...
This lists of mines in India is subsidiary to the list of mines article, and future mines in the country and is organised by the primary mineral output. For practical purposes stone, marbles and other quarries may be included in this list. In India, the underground mine to surface mine ratio is 20:80 [citation needed].
The Stockton mine railway was, in 1908, New Zealand’s first electric railway. It carried coal from the Westport-Stockton Coal Companies mine to the NZR railhead at Ngakawau on the West Coast of the South Island from 1908 to 1953, when it was replaced by an aerial cableway. The line was 10.5 km long, with 2.4 km in two long tunnels.
The largest consumer and importer of coal is China. China mines almost half the world's coal, followed by India with about a tenth. Australia accounts for about a third of world coal exports, followed by Indonesia and Russia. [5] Coal is largely held in the Earth in areas that it needs to be mined from, and is generally present in coal seams.
A coalfield is an area of certain uniform characteristics where coal is mined. The criteria for determining the approximate boundary of a coalfield are geographical and cultural, in addition to geological. A coalfield often groups the seams of coal, railroad companies, cultural groups, and watersheds and other geographical considerations.
The move broke the monopoly over commercial mining that state-owned Coal India has enjoyed since nationalisation in 1973. [19] The Coking Coal Mines (Nationalization) Act, 1972 and the Coal Mines (Nationalization) Act, 1973 were repealed by the Repealing and Amending (Second) Act, 2017 on 8 January 2018. [20]
