In the\u00a0United Kingdom<\/a>\u00a0and\u00a0South Africa<\/a>, a coal mine and its structures are a\u00a0colliery<\/b>, a coal mine is called a ‘pit’, and the above-ground structures are a ‘pit head<\/a>‘. In\u00a0Australia<\/a>, “colliery” generally refers to an underground coal mine. [Wikipedia<\/strong><\/a>]<\/em><\/p><\/blockquote>\n

The colliery\u2019s coal wouldn\u2019t fuel polluting power stations. Instead, the mine would supply \u201ccoking coal\u201d to the steel industry in the UK and Europe. Coke is a dense form of carbon that plays three vital roles in steel-making. Inside a blast furnace, carbon chemically removes oxygen from iron oxide ore to create crude iron. Burning coke also raises the temperature to 2000\u00b0C or more, allowing molten iron to be tapped from the bottom of the furnace. Finally, a dash of carbon in the iron strengthens the metal, helping it to become steel inside a second furnace.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"
