Horizontal Waterjet Exploration of Burning Coal Seams
A 1. 5 m high coal seam is burning on the bank of the Yellowstone River near Sidney, Montana. A high pressure waterjet drilling unit was used to create small holes through the burning zone in order to site thermocouple arrays used to identify the size of the fire. The ability of the jets to mine the burning material was examined as a possible means of excavating the fire. Problems encountered included the total loss of water to steam and into the cracked rock, making it very difficult to clear debris from the hole.
