Locating the endogenous fre source in a coal mine wall by electrical prospecting

Conclusions and application of research results.The electrical sounding method can be efficiently used to detect and localize endogenous fire sources in coal masses at all stages of fire.At the self-heating stage, the geometry of the anomaly can be estimated from the electrical profiling data.When a fire develops in the pit wall, multi-electrode installations (electric tomographs) are promising for the fire zone boundaries determination.
