<p>A method for recovering a coal seam, or an organic substance or fossil organic substance under the ground by a process of non-combustion gasification at the original location thereof, which comprises pressing supercritical carbon dioxide from the face of the ground into the coal seam or a rock zone (1) containing the organic substance or fossil organic substance under the ground, to thereby extract volatile components from the coal seam or rock zone (1), and recovering the volatile components to the face of the ground. The method allows the effective use of a coal seam or a rock zone containing an organic substance or fossil organic substance under the ground, without mining and by a non-combustion process, and further with a reduced cost and safety.</p> |
