Underground coal gasification

AIChE Journal, 1978
AbstractUnderground coal gasification (UCG) is a method whereby the mining and conversion of coal are accomplished in a single step. Many field tests of UCG have been operated worldwide since the 1930's with varying degrees of success; based on this experience (especially in the USSR and United States), a field design which is applicable to a wide ...

Underground gasification of coal and lignite

Coke and Chemistry, 2016
The underground gasification of coal and lignite is of interest when traditional coal extraction is impossible or unprofitable and also with increasing demand for thermal and/or electric power. In the Soviet Union, at six industrial Podzemgaz stations, beginning in the 1930s, more than 15 million t of coal was processed to obtain more than 50 billion ...

Economics of Underground Coal Gasification

1981
As with other coal utilisation processes, economics will be decisive in determining the degree of exploitation of a technically feasible operation. In the case of Underground Coal Gasification (UCG) there are several important economic questions: (1) How does UCG compare with other methods of exploiting coal resources?
