Abstract.

This article points such pressing issues as methane recovery from the coal deposits, its use as an alternative energy source, and its reserves on the territory of Ukraine. A new approach to mining the deposits with geological resources is presented which considers the coal mines as enterprises for mining gas-and-coal deposits. A method for borehole completion is described which impacts by a carbon-containing component, such as methane, which is released into the borehole from the gas-saturated coal-rock mass. The impact was industrially tested in the A.F. Zasyadko Mine where basic algorithms and dependences of the method of coal-and-rock mass degassing were used for intensifying the methane recovery through the surface degasification boreholes and with applied pneumohydrodynamic impact.

Keywords:

intensification, coalbed methane, surface degassing boreholes, production rate, coal-and-rock massif.
