Abstract.

Methane is one of basic gases  having  considerable influence on a hotbed effect in the atmospheric environment of the planet Earth. His negative potential is estimated by scientists in 20 times higher, than the proper influencing of dioxide of carbon. There is the troop landing of passing hydrocarbon gases in an environment at development of coal deposits. From the mines of Ukraine approximately 2060 million сubic meters acts on a surface.from which approximately only 15% is extracted by the systems of degassing and 7% is utilized.

The aim of this study was to create a method for producing hydrates from methane or other hydrocarbon gases for further use, storage and transportation.

In this scientific paper, kinetics of hydrate formation was studied and a problem of accelerating the formation of artificial gas hydrates was solved by way of physical and chemical impact on the process of their structuring with simultaneous formation of homogeneous mass due to the surface activation of water molecules, which eliminated reversibility of the process and significantly increased amount and quality of the finished product. The needed laboratory equipment was designed in order to create gas hydrates from gas of different chemical composition and percentage of methane content. Problem of mine methane utilization in continuous cycle directly from the degassing wells while carrying out the corresponding operations was solved.

Will be drawn on result of researches for development and creation of the industrial mobile setting for creation of gas hydrates, which will provide utilization and use of methane  of gas-coal deposits and gas supplies of small and middle volume, before regards  non-liquid. They  make it possible not only to use gas from the degassing wells as an additional source of energy, but also to reduce harmful emissions of methane into the atmosphere by transferring it to the gas hydrate state. In addition, the recommended gas hydrate technology makes it possible to increase safety during transportation of gas and to reduce its consumption. To improve the process of artificial gas hydrates formation, it is proposed to create an industrial and experimental installation with equipment that would allow to conduct studies at the molecular level.

Key words: additional energy source, gas hydrate, mine methane, methane utilization, degasification well.
