Аnnotation

The fire and explosion hazard of landfills is analyzed taking into account the trends of introduction of biogas (methane) collection and utilization. According to the results of analysis and synthesis of factors of occurrence and spread of man-caused danger, available mathematical models and methods of counteraction to man-caused danger, the authors determined the initial and boundary conditions of is the basis for further development of appropriate methods of emergency response. During the analysis it was found that humidity, temperature of the landfill, the presence of sufficient oxygen at a certain point in time initiate the formation of explosive concentrations of methane in the array and contribute to the spread of hazards in landfills. The specific weight of the organic component, the value of the density of the array, the height of waste disposal affect the process of counteracting the danger, namely preventing a dangerous event and preventing the emergency from the object to the highest level of distribution, primarily in the first priority group, such as the number of victims and injured civilians and specialists of the State Emergency Service of Ukraine. A system of communication equations is determined by synthesis, taking into account the initial and boundary conditions of the mathematical apparatus, which allows to further develop a control algorithm for emergency response related to fire and explosion hazardous landfills close to settlements. Further research is aimed at: establishing the area of effective solutions for the choice of variation of solutions of individual problems to assess these indicators of the initial and boundary conditions of the mathematical apparatus in the development of emergency response methods associated with fire and explosion hazards; to develop a control algorithm for the appropriate methodology and verify its reliability
