Coal River was the first name given by British settlers to the Hunter River after coal was found there in 1795. In 1804 the Sydney-based administration established a permanent convict settlement near the mouth of the Hunter River to mine and load the coal, predetermining the town's future as a coal port by naming it Newcastle.
The Nord-Pas-de-Calais Mining Basin is a mining basin in Northern France that stretches across the Nord and Pas-de-Calais departments. The region is famous for its long history of coal extraction and its testimony to a significant period in the history of industrialisation in Europe, and as a result it was inscribed on the UNESCO World Heritage List in 2012.

Subbituminous coal can form at temperatures as low as 35 to 80 °C (95 to 176 °F) while anthracite requires a temperature of at least 180 to 245 °C (356 to 473 °F). [24] Although coal is known from most geologic periods, 90% of all coal beds were deposited in the Carboniferous and Permian periods. [25]
The name Carboniferous means "coal-bearing", from the Latin carbō ("coal") and ferō ("bear, carry"), and refers to the many coal beds formed globally during that time. [8] The first of the modern "system" names, it was coined by geologists William Conybeare and William Phillips in 1822, [9] based on a study of the British rock succession.
The national coal strike of 1912 was the first national strike by coal miners in Britain. Its main goal of securing a minimum wage. Its main goal of securing a minimum wage. After a million men had walked out for 37 days, the UK Government intervened and ended the strike by passing a minimum wage law. [ 16 ]
Mining in France is based solely on the nature of the material, whether extracted from the surface or underground. These include fuels (coal, hydrocarbons, gas), metals (iron, copper) and a few other minerals (salt, sulfur). The inventory of mining resources is relatively well known for surface and subsurface deposits.
The latter developed a cross pattern in the resulting structures – the well known Variscan x. The intensive nappe-stacking during continental collision transported high-grade terranes in a southerly direction over less deformed units creating the impression of an inverted metamorphism – a feature so ubiquitous in the Massif Central.
Coal forest of tree ferns and lycopod trees, in a 1906 artist's rendering. The coal forests seem to have been areas of flat, low-lying swampy areas with rivers flowing through from higher, drier land. [4] When the rivers flooded, silt gradually built up into natural levees. Lakes formed as some areas subsided, while formerly wet areas became ...
