(DE19703448-A1)      The rate of production of methane from a water-containing subterranean coal formation penetrated by at least one well is increased by injecting an aqueous oxidant solution (I) into the coal formation. By maintaining (I) in the coal formation, the formation of cleats is enhanced or stimulated.    The oxidant preferably comprises hypochlorite, hypochlorous acid metallic salt, hydrogen peroxide, ozone and/or oxygen, especially hydrogen peroxide or ozone.    USE -   The process can be carried out prior to the use of gas sweep or gas desorption treatments for methane recovery.    ADVANTAGE -   The cleat systems provide channel ways through which water and methane can migrate to the production wells for removal.
