NEW MEXICO EMNRD: Coal Fire Characterization

Coal Sector
Three fires that are burning on the Navajo Nation were characterized under this contract using a three phase approach. In Phase 1, general geological information at each of the fire sites was documented. In Phase 2, field data, including methane flux, magnetic anomalies, gas compositions, and relevant surface features, was collected, analyzed, and integrated in order to generate a conceptual picture of how the coal fire was consuming the coal in the subsurface. Areas affected by the coal fire were also delineated. In Phase 3, recommendations were made to the Navajo AML regarding future actions to take at each of the three fire locations. Based on our characterization efforts, one of the three fires was successfully excavated and extinguished.
