Abstract

A process for maximization and optimization of coal energy comprising the steps of Selection of old coal mine or coal bearing areas; surveying of the mine or coal bearing areas for preparing of the panels; hydro-geological survey and Geo- Mechanical survey of the panels of Step-ll above; sub paneling and slicing of the survey panels of the step-ll and III above; preparing of the surface of the panel of step-IV above for development for at least boring of the panels; underground/Channeling of the boreholes at the floor level of the coal; burning of the coal in said channel of step-vi; extraction of the heat from the prepared boreholes seam & simultaneously filling of the voids created by extraction; use of the extraction heat for conversion into steam energy; use of the steam energy for generation of electricity or any other alternate use.
