Abstract

The conditions of natural gas hydrates formation were studied experimentally. The composition of natural gas was determined chromatographically. The equilibrium points of the natural gas hydrate on the P-T diagram are determined. It was found that the point of natural gas hydrate formation is always below the equilibrium curve of methane hydrate. In the band of positive temperatures of coal seams, the decomposition of natural gas hydrates creates an additional amount of gas, which can affect the formation of outburst hazard situations in the marginal zone of coal seams.
