Abstract

As an aid in the design of an electromagnetic system for the detection, monitoring, and mapping of the burn front of an underground (in situ) coal gasification process, an analytical model has been developed that will predict the electromagnetic field reflected from the gasified portion of the coal seam. Indications are that a swept frequency monitoring system is capable of locating the burn front of the in situ gasification process, with the vertical electric dipole being the most attractive element.
