The coal mining life cycle Mining for schools

The coal mining life cycle. Exploration. Coal exploration includes gathering data, which allows for decisions to be made on the desirability of further exploration, the technical feasibility of mining, and economic feasibility including the size of the mine and the quality of the coal. Geologic mapping, aerial photography and photogrammetry are all used in exploration. Drilling is the most

Coal mining

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit', and the above-ground structures are a 'pit head'. In Australia, "colliery" generally refers to an underground coal mine.

Model of environmental life cycle assessment for coal

The primary novelty of the paper is the development of a computational environmental life cycle assessment (LCA) model for coal mining operations and the application of the model for coal mining operations in Poland. The LCA model enables the assessment of environmental indicators for all identified unit processes in hard coal mines with the life cycle approach. The proposed model

Coal National Geographic Society

22/12/2012 Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity.
