description The utility model relates to a working face air leakage sampling detection device which comprises a sampling pipe, a multi-way valve, a hole packer, an air guide pipe, a U-shaped water column meter, control valves and a connecting pipe head, the front end of the air guide pipe is communicated with the multi-way valve, the tail end of the air guide pipe is communicated with the sampling pipe, the multi-way valve is further communicated with the U-shaped water column meter and the control valves, and at least one control valve is communicated with the connecting pipe head through a flow guide pipe. The gas guide tube is coated with the hole packer, and the sampling tube comprises a tube body, a sealing plug, a sealing ring and a protection cone. The device is simple in structure, flexible and convenient to carry, assemble and position, and capable of effectively meeting the requirements of detection operation of various roadway structures, effectively improving the gas leakage detection efficiency, effectively
