FIELD: mining engineering.
SUBSTANCE: invention relates to safety field and prevention of endogenous fires during underground mining of coal beds prone to spontaneous combustion. The method for detecting underground fires is proposed, which includes conducting electrical exploration with measurement of specific resistivity, the width of the beds of the geoelectrical section, and the determination of coal temperature t in the area abnormality. The method is carried out from the earth surface, and coal temperature t in the area of abnormality is determined taking into account the electrical exploration of the geoelectrical section and the properties of coal.
EFFECT: increased efficiency and accuracy of underground fire sources location, reduced costs for extinguishing fires and improved safety of mining operations.
