Extraction of methane from the closed mine "Moszczenica”

Abstract

Closed methane hard coal mines may become a source of methane used in the energy industry. There are many unliquidated tunnel workings left, they contain lot of workings with a large capacity of free space, and a network of cracks formed in the rock mass. Release of methane to the atmosphere is practically reduced to zero. Closed mines can be a source of methane used to produce energy. This article presents the example of the "Moszczenica" mine as a source of methane, which is captured and converted into electricity and heat.
