Coal geology and coal technology | Nadir Buksh · The coal is then ignited in a controlled manner to produced hot, coustible composite gas (a mixture of CH4, CO, CO2 and H2) which are captured by the production wells. This synthetic gas may be collected at the surface and purified for power generation.
Coal mining typically uses two methods –the surface and the underground techniques, and choice is primarily determined by geological factors. In Zimbabwe coal depth is the main determinant. Environmental and social factors confined to determining whether the deposit will be mined or not. First Zimbabwean coal left the mine at Hwange for the

Over the lifetime of the program, approximately 100 million supported nearly 1,000 projects with coal research and development work focusing on carbon management, advanced coal mining technologies, power generation and plant efficiencies, flue gas cleaning and coal chemistry.
Coal mining Coal mining Coal deposits: In geologic terms, coal is a sedimentary rock containing a mixture of constituents, mostly of vegetal origin. Vegetal matter is composed mainly of carbon, hydrogen, oxygen, nitrogen, sulfur, and some inorganic mineral elements. When this material decays under water, in the absence of oxygen, the carbon content increases.

The gas composition depends on the coal geology as well as the process parameters. It can be produced using a variety of oxidants, including air and oxygenrich gaseous blends. Process parameters such as operating pressure, outlet temperature and flow are governed by the coal and rock properties that vary with time and location.
The International Journal of Coal Geology deals with fundamental and applied aspects of the geology and petrology of coal, oil/gas source rocks and shale gas resources. The journal aims to advance the exploration, exploitation and utilization of these resources, and to stimulate environmental awareness as well as advancement of engineering for effective resource management.
