Coal Production - an overview ScienceDirect Topics

The increased coal production worldwide through underground mining led to explosions of gas (e.g. methane and carbon dioxide) and coal from the working mine face. Outburst was not a problem when coal was mined from outcrops and shallow shafting in Great Britain and Europe because gas was easily liberated to the atmosphere.

Coal Analysis and Production Information Thermo

Coal is a common energy source in the steel industry to extract iron from iron ore, and in the cement production process. The four main types of coal are lignite, sub-bituminous, bituminous, and anthracite. Each type has varying amounts of hydrogen, oxygen, nitrogen, sulphur, and carbon, and as a result they have different uses.

How plastics are made :: PlasticsEurope

Plastics are derived from natural, organic materials such as cellulose, coal, natural gas, salt and, of course, crude oil. Crude oil is a complex mixture of thousands of compounds and needs to be processed before it can be used. The production of plastics begins with the distillation of crude oil in an oil refinery.
