FIELD: mining.
SUBSTANCE: trapping method of methane involves suction of methane through connection pipe of tight chamber during development of coal bed. Tight chamber is installed on supports above outlet air flow of the well. Connection pipe is located in upper part of chamber, and air is discharged in natural manner through lower part. At that, together with methane suction through connection pipe in upper part of the chamber, its percentage is measured.
EFFECT: simplifying methane trapping and reducing electric energy costs.
