The utility model belongs to the technical field of coal mine safety, concretely relates to high testing arrangement of coal containing methane imbibition not. There is not effective way to grasp moisture, radius of wetted bulb in the coal body at present, the consequently parameter (water injection time and water injection hole pitch) in unable equitable definite water injection hole, these barriers have hindered the disappear development of abrupt measure of coal seam infusion. In order to solve the problem, the utility model provides a testing arrangement of coal containing methane imbibition height does not include that moulded coal, uniform section basin, the sponge of certain thickness, PVC behind the special treatment manage and the suction pump. Draw water in suction pump circulation, the water injection guarantees under the unchangeable condition of moulded coal bottom imbibition water level, through water -sensitive colored indicator real -time reading imbibition height, hasguaranteed the reliability of research, prevent abrupt mechanism and lay solid theoretical foundation for recognizing the water injection of coal cleaner layer, and then provide the guidance of scientific theory for the sureness of on -the -spot coal seam infusion parameter to reduce coal seam gas content, realize coal safety efficient mining.
