The Underground Electrocarbonization And Gasification Of Mineral Fuels, Erich Sarapuu
Doctoral Dissertations
"The development of underground gasification methods for recovering mineral fuels is comparatively recent and several methods have been evolved for treating the various source materials. The problem of recovering solid and liquid fuels by underground gasification in gaseous form was primarily approached by means of opening underground entries which created the required fire-drift for starting the gasification in place.
Increasing knowledge of the whole problem of gasification in situ led to the evolution of new improvements in the underground gasification technique and, in the course of progressive research the preparations required for starting the gasification were accomplished from the surface. …
