European Coal Geology and Technology (Geological Society Special Publications)
Home Contact. Part 1. Chemical characteristics Relationships between chemical and mineral composition of coal and their potential applications as genetic indicators.
Part 2. Coal Geology Coal Geology provides a complete integrated handbook on coal and all its properties, covering the physical and chemical properties of coal as well as coal petrology. It describes the age and occurence of coal; coal sampling and analysis; coal exploration; geophysics and hydrogeology of coal and coal mining techniques. It also discusses environmental concerns and computer technology, and includes an update on global coal reserves and production figures.
Coal Geology Research Progress Coal geology is the study of a field that concentrates on the origin, occurring relationships and geological characteristics of coal and similarly treated rocks. This field is also involved in the study of coal-derived gases, fluids, both naturally occurring and man-made solid coal by-products.
This book presents state-of-the art research from around the world. European Coal Geology And Technology Despite the decline in the coal mining industry across Europe during the last decade, coal continues to supply a major part of the growing energy requirements,particularly in the developing countries. During this period there has been a shift in coal extraction techniques from deep underground mines to open pits, reflecting cheaper production costs in a market economy. Coal occurs as layers or seams, ranging in thickness from millimetres to many tens of metres.

It is composed mostly of carbon 50—98 per cent , hydrogen 3—13 per cent and oxygen, and smaller amounts of nitrogen, sulphur and other elements. It also contains water and particles of other inorganic matter. When burnt, coal releases energy as heat which has a variety of uses. Coal is broadly separated into brown and black which have different thermal properties and uses. Brown coal lignite has a low energy and high ash content. Brown coal is unsuitable for export and is used to generate electricity in power stations located at or near the mine.

Black coal is harder than brown coal and has a higher energy content. In Australia anthracite, bituminous and sub-bituminous coals are called black coal whereas in Europe, sub-bituminous coal is referred to as brown coal table 5. Coal consumption declined due to the increased supply of cheaper and cleaner natural gas, growth of renewable energy sources, and rigorous environmental regulations.

Data from: U. Coal in Indiana was discovered along the banks of the Wabash River in Coal production declined following World War I, but underground deep mining remained the primary mining method in Indiana until the s. Surface mining continues to be the primary method of coal removal in Indiana, with nearly 70 percent of the current production coming from surface mines. Indiana has approximately 57 billion tons of unmined coal, of which nearly 17 billion tons is recoverable using current technology.
Of the mineable reserves, about 88 percent is recoverable by underground mining and only 12 percent is recoverable usingsurface mining methods. Based on current production rates, Indiana's 17 billion tons of available coal could last more than years. Menu Search. Bookstore Sign In.
