In three underground coal gasification experiments at the Hoe Creek site near Gillette, WY, LLNL applied three different linking methods: explosive fracture, reverse burning, and directional drilling. Air was injected in all three experiments; a steam/oxygen mixture, during 2 days of the second and most of the third experiment. Comparison of results show that the type of linking method did not influence gas quality. The heat of combustion of the product gas was higher with steam/oxygen injection, mainly because of reduced inert diluent. Gas quality was generally independent of other operating parameters but declined from its initial value over a period of time because of heat loss to the wet overburden and extensive roof collapse in the second and third experiments.
