FIELD: power engineering, possible use for manufacturing gas by organizations responsible for current and perspective provision of gas to population and industrial objects.
SUBSTANCE: method includes drilling the well from surface, heating coal bed through, localization and extraction of gasification products. Well is drilled in trap roof, opened serially are gas-impenetrable cover, coal bed or coal-yielding depth, water level, from which thermal bed water - heat carrier along borehole is injected into coal bed for its heating. Existing carbonization is increased with escape of gas until stabilization of temperature balance in space localized by trap limits. Gas is extracted through perforation of well wall in interval of collector bedding below cover in the trap roof. Between roof of coal bed and shoe of collector below the cover, borehole is blocked.
EFFECT: increased existing carbonization due to usage of depth heat.
