Abstract
The article presents the suitability of polish lignite deposits for clean coal technologies, mainly fluidized bed gasification and underground gasification. One of the key elements in this study, is a detailed diagnosis of the resource base, its analysis on the basis of the established verification criteria and -as a result - the achievement of a reliable assessment of suitability for highly efficient production of fuels and electric energy through lignite gasification in both surface and underground installations, taking into account both sozological conditions and protected geological sites.
The analysis has shown that only 10 out of from 166 lignite deposit meet the criteria for the potential development of process underground gasification.
Actual State of Underground Gasification of Coal and Future Problems
