Abstract

The analysis of sudden outbursts of coal and gas in coal mines is presented in the article. Phase transitions of gas to gashydrate state are investigated in the laboratory. Thermobaric parameters of phase transitions of mine methane are established. The new hypothesis is described of sudden outbursts of gas that is based on a gashydrate condition of methane in mines at depths (near 1000 m and more) and their explosion-like failure – Percy Bridgman’s effect.
