The phenomenon of destruction of chemical bonds of molecules in the field of point electric charge is established, on the basis of which the physical mechanism of catalytic action of point charge is proposed, and the model of dynamics of elementary acts is developed, reflecting the physicochemical features of high-speed reactions in the mine atmosphere, conditions and conditions surface processes in non-equilibrium low-temperature gas discharge plasma. The theoretical substantiation of the

... tiation of the physical mechanism of the influence of point charges of plasma in the interval between the electrodes on the stability of chemical bonds of molecules, which made it possible to solve the problem of negative influence of arc-extinguishing processes in the explosion-proof shells and to increase the reliability of the control and operation of the technology. It is intended for specialists in the field of safety of industrial equipment in transport systems and underground power supply. It may be useful to experts in the development of explosion-proof electrical equipment, graduate students, and students of relevant specialties.
