The paper describes the first long-term underground coal gasification experiment with oxygen-steam injection. In the Hoe Creek No. 3 underground experiment, linkage paths were established between the injection and production wells by drilling a horizontal borehole between them near the bottom of the coal seam. The drilled linkage hole was enlarged by reverse burning, and then the forward gasification process was started - first with air injection for one week, then with oxygen-steam injection for the remainder of the experiment. During the oxygen-steam injection period, about 3900 tons of coal were gasified in 47 days, at an average rate of 83 tons per day. The heating value of the dry product gas averaged 218 Btu/scf, suitable for input to a processing plant for upgrading to pipeline quality, which is about 900 Btu/scf.
