Формування умов розробки математичного апарату попередження надзвичайних ситуацій в тунелях

Abstract

The paper considers the solution of the problem of increasing the efficiency of the process of prevention of terrorist emergencies in the tunnels of railway transport. Within the framework of the set scientific task the current state of the issue of formation of the mathematical apparatus of methods of counteraction to emergency situations of terrorist character in railway tunnels is analyzed. The physical field and conditions of formation of the mathematical model of prevention of emergencies of terrorist character in railway tunnels and the corresponding technique on its basis are defined. At the final stage of solving the scientific problem, the basic equations of the mathematical model of prevention. In the course of successive solution of the tasks, the existing contradictions in the physical field of model formation are identified and a clear range of functional limitations is formed. Accordingly, the control algorithm of the method should take into account the multilevel liquidation works and the corresponding preliminary procedures for calculating the parameters of the extinguishing pulse and determining the minimum possible distance of blasting, taking into account the risk of pyrotechnics by fragments and structural elements of the railway tunnel. The results obtained in the work allow to further develop a number of practical recommendations for improving the existing standard operating procedures in the case of using additional protection devices and methods of its application in order to reduce the time of localization of terrorist emergencies in railway tunnels, preventing their growth to a higher level of danger, and ensuring a sufficiently high level of individual and collective protection of SES personnel and civilians
