The industrial production of coke from coal is called coking.The coal is baked in an airless kiln, a "coke furnace" or "coking oven", at temperatures as high as 2,000 °C (3,600 °F) but usually around 1,000–1,100 °C (1,800–2,000 °F). This process vaporizes or decomposes organic substances in the coal, driving off volatile products, including water, in the form of coal-gas and coal .
The primary method of coal extraction at the Tahmoor Coking Mine until 1987 was Bord and Pillar mining, after which longwall mining was introduced. The majority of coal is now extracted from the mine using the longwall mining system, with a much smaller part coming from the mine development. The CHPP is able to process 650 tonnes per hour and ...
