CHARACTERISTICS OF METHANE RELEASE IN HIGHLY PRODUCTIVE COAL MINES

摘要

The article discusses the research of methane release intensity versus average daily output in coal minesfeaturing different geological and mining conditions in Vorkuta and Kuznetsk Coal Basins. The authorsdescribe degassing of producing and superimposed methane-bearing coal beds in highly productivelongwalls, at the stages of coal face output of 26 thousand tonnes per day and in the first months ofoperation.
