The article is devoted to the study of the problem of spontaneous combustion of energy grades of coal not only during storage, but also during transportation. As the main samples for the study, the energy grades of SS and Zh coals were selected. The main task of the scientific research was to study the rate of cooling and heating of coal depending on their thermophysical parameters and environmental parameters. To solve this problem, the authors used both the author's installations designed to study the thermophysical parameters of the spontaneous combustion process (the Ya.S.Kiselev method), and the NETZSCH STA 449 F3 Jupiter synchronous thermal analysis device, the NETZSCH Proteus Termal Analysis software package. On the basis of a complex study of the spontaneous combustion process, the authors of the article obtained the kinetic characteristics of the spontaneous heating process (activation energy and pre-exponential multiplier). Nomograms of the permissible size of coal density of different types and shapes of accumulation depending on the ambient temperature are presented, practical recommendations for the prevention (avoidance) of spontaneous combustion of coal fuel are given.

Introduction. A brief analysis of catastrophic fires and explosions on the offshore oil platform, ships and vessels is performed. It’s shown the relevance of the qualitative improvement of marine fire equipment. Analysis of modern fire fighting systems on vessels, ships: sprinkler, deluge, gas and pneumatic-impulse fire extinguishing systems is carried out. It’s substantiated new equipment for upgrading existing systems — subsystems of multi-module pulse, vortex combined quenching for the protection of ships, vessels, tankers, offshore oil platforms. The choice of the arrangement of modules based on the results of polygon tests is described. There are created systems of modules for the upper decks, engine rooms, holds, corridors, gangways, sections, electrical cabinets, etc.The modules create gas-water squalls, gas-powder vortices that extinguish all fires and continuous fires in all or part of the compartment and deck in seconds. The participation of pilot modules in operations for eliminating the consequences of disasters in hard-to-reach zones of collapses, with high levels of radioactive and toxic contamination in emergency locations is described.Description and analysis of experiments. The recommendations on the use of multi-barrel modules based on the analysis of experiments on the creation of fine-dispersed water squalls for extinguishing developed fires of classes A, B, C, F, the inhibition of explosive vapor-air clouds, the deposition and detoxification of gas-air clouds of ammonia and chlorine are substantiated and developed. The localization and liquidation of oil and oil products are described. The possibility of reducing the cost of liquidation of 1 sq m of bottling from $ 20-40 to $ 1-3 is shown, and reducing the time for liquidation of bottles to 5-10 times, which in a more multiple degree will reduce material and environmental losses from oil bottling.Conclusion. The advantages of introducing new technology and techniques for eliminating the consequences of accidents at sea and preventing their development into a catastrophe are summarized.
