Method for removing methane from coal |
摘要 |
A process for removing methane from a subterranean coal deposit. A carbon dioxide-containing fluid is introduced into the coal deposit through an injection well and held therein for a period sufficient to enable a substantial amount of methane to be desorbed from the surfaces of the coal deposit. Following the hold period, the injected carbon dioxide-containing fluid and desorbed methane are recovered through a recovery well or wells spaced from the injection well. The process is repeated until sufficient methane has been removed to enable safe mining of the coal deposit.
