At the same time, measuring low-voltage circuits are an important integral component of diagnostics and information content of mining equipment control systems. This is due to the fact that the theory and models of the ignition of a methane-air mine atmosphere (MMA) solve problems in a narrow setting and cannot be used in the general mine case. The article <br />identifies the conditions and parameters for the ignition of the MMA from the low-voltage measuring circuit (NVC),developed criteria for the ignition of the form the NVC, the existing model of the possible ignition process of the MMA from the NVTs is finalized. Currently, there are two theories of ignition of the HCV: thermal and ionic. From the author’s point of view, the thermal model of VSH ignition from the electric discharge of the NSC is based on the analysis of the propagation of the temperature wave from some heat source in an inert environment. The thermal <br />ignition model of VHS does not take into account many details of the physics of the combustion mechanism, such as the chain nature of individual acts of chemical interaction, the activation energy of molecules in the formation of active centers, and it is based on postulating some electric discharge. An assessment of the intrinsic safety and the possibility of self-expansion of the NVC flame core has been carried out. The approbation of research at three foreign conferences and the interest of foreign colleagues in them are shown.
