The article investigates the nature of changes in the level of radiation and absorption of electromagnetic oscillations by coal samples that are in an extremely stressful state. When performing the work, a stand of studying electromagnetic oscillations was assembled for different levels of compression stress of the rock. The results of changes in the amplitude of electromagnetic oscillations in the frequency range 0.5-1.5 and 66–110 MHz for different values of compressive stresses of coal sample
