Lekhtman I. Forecasting and the prevention of explosions of a mix of methane air in the installed gas rooms

The object of study - the processes of explosion in the formation of methane and dangerous environment of an ignition source in the gasified areas. The aim is the establishment of the influence factors spill methane in gasified room on the probability of an explosion and improve on this method-based assessment and forecasting to support effective measures and means to prevent such accidents. When the dissertation research for an integrated approach, which includes: analysis and synthesis of previous studies explosion gasified premises, systems analysis to establish causal relationships between the factors that influence the formation of explosive atmospheres, ignition sources and heat of explosion, and methods of probability theory to calculate Explosion levels in gasified room; reliability theory of explosion protection, laboratory testing and implementation of the developed methods and automatic means to prevent explosions in the premises, methods of mathematical statistics to process the results of experimental studies, mathematical modeling using computer applications MathCAD and Excel. The practical significance of these results is to introduce the following technical solutions: the experimental model system for explosion gasified areas which is achieved through continuous monitoring of the gas concentration in the room and in the opening pressure gas pipeline, as well as by eliminating the possibility of the appearance of a dangerous source, can prevent the occurrence of accidents and to increase Explosion levels of such premises; experimental models of two shut-off valves installed on the premises introductory pipeline for emergency gas shut-off. Obtained in analytical relations have become the basis for the development of the industry regulatory document "Methodology for assessing the level of security of electricity supply systems and gas field production facilities, which can form an explosive gas-air mixture." This technique was developed SHEI "Donetsk National Technical University," and the Russian State University of Oil and Gas. IM Gubkin and approved by "Gazprom" (Russia) in 2012 The results are used in the educational process at the department "Power industries and cities" SHEI "Donetsk National Technical University" with training and master the course "Reliability and Diagnostics of electrical systems" . Scope of the work - the fuel and energy complex and the national economy.
