| Sumari: | Title screen Infrared glow in fan-shaped boreholes was studied and measured along four cardinal directions and in vertical direction in block 12, northwestern site, sublevel 6, horizon minus 210, the Tashtagol iron ore mine. It is shown that the difference in the glow temperature can reach 3° C in the eastern direction and in vertical fan-shaped boreholes. The results were obtained for physical modeling of the glow in the holes of the magnetite ore samples. The patterns of changes in the intensity of infrared glow of the magnetite ore samples under uniaxial or shear compression are shown. The changes in the infrared glow temperature are found to correspond to the stages of fracture development. In this case, the temperature of the IR glow changes in accordance with the stages of fracture development. Changes in the electromagnetic emission are given in accordance with the stages of preparation and development of fracture of the magnetite ore sample of similar structure. Possible mechanisms of energy supply for heating rocks in the vicinity of boreholes and holes are discussed. The data obtained indicate the efficiency of IR thermometry for detection of stressed rock massif areas in the vicinity of boreholes with increased glow intensity.
