Fecha de publicación: 22/12/2022 Fuente: WIPO (eseential oils OR extracts) A coalbed methane coal gas mine is disclosed. In the mine, a plurality of coalbed methane and coal gas stoping working faces alternately take over production. Each work face first extracts coalbed methane from a working face coal seam by using an isobaric coalbed methane extraction hole (11). Then, in a ventilation and gas injection coal tunnel (8) for extracting the coalbed methane, a gasification agent oxygen pipeline and a gasification agent water vapor pipeline are installed. A working face coal gas coal channel (9) in the working face coal seam connects a plurality of gasification coal channels (10, 28). A plurality of mine gasification furnaces are arranged on the two sides of each gasification coal channel. An air injection pipe (30) of each mine gasification furnace is connected to an oxygen pipeline and a water vapor pipeline in the ventilation coal channel. After an electric furnace in each mine gasification furnace is ignited, oxygen and water vapor are injected by means of the gas injection pipeline to produce coal gas, and the coal gas sequentially flows into the gasification coal channel, the working face coal gas coal channel, and a coal gas wellbore to reach a ground pipeline. The present mine is suitable for various coal seam geological conditions.
