Abstract

The present invention relates to a method of producing syngas from an underground coal deposit, comprising the steps of providing an injection well into the coal seam; providing a production well into the underground coal seam; providing a linkage bore in the coal seam running from the injection well to the production well; providing a laser into the linkage bore; heating the coal located in the linkage bore with the laser; producing syngas; and extracting the syngas through the production well.
