Underground coal gasification (UCG) involves the gasification of coal in the coal seam so that the gas can be utilised for power generation. The concept is simple, but the development of a controllable process has proved difficult with the available technologies up to the early 1990s. Generally UCG was restricted to shallow coal
This paper presents the results of an extensive experimental analysis of underground coal gasification (UCG) using large bulk samples in an ex-situ reactor under atmospheric and high-pressure (30 bar) conditions. The high-rank coal obtained from the South Wales (UK) coalfield is employed for that purpose. The aim of this investigation is to define the gas production rates, gas composition, gas ...
Underground Coal Gasification (UCG) is a process for exploiting coal that cannot be mined because the seams are too deep, thin or fractured. The process involves using the same sort of drilling technology usually used for fracking to get air/oxygen into the coal seam and then set the seam on fire.
In the provisions of Coal Authority ("the Authority") conditional coal mining licences an extension of the conditional term can be permitted, subject to:

Mar 18, 2012· Underground Coal Gasification (UCG) involves utilising the drilling technology normally associated with oil and gas extraction to get access to coal that is not possible to mine with conventional means (tunnels or open cast). Since you cannot pump solid coal up a well bore it needs to be first converted into a liquid or gas.

Underground Coal Gasification (UCG) is the conversion of coal with a controlled combustion (in situ underground) into a synthetic gas that is then extracted and processed to provide fuel for power generation or fuel oils. The gas contains both methane and hydrogen and it can be processed into a high quality diesel using the Fischer-Tropsch ...

The UK was the originator of underground coal gasification (UCG) technology almost a century ago, when Sir William Ramsay conducted exploratory experiments beneath Hett Hill in County Durham in 1912. World War I put a stop to these experiments, and UCG was later neglected in the UK while its abundant domestic reserves of oil and gas were exploited.
