Novel exhaust device for paste filling closed partition wall

The utility model relates to a novel exhaust device for a paste filling closed partition wall, and belongs to the technical field of mining exhaust devices. The device comprises a partition wall, an observation pipe, a gate and an exhaust gap, the partition wall is arranged at the outlet end of a room goaf, the observation pipe extending outwards is installed on the partition wall along the opposite face of the room goaf, the other end of the observation pipe is communicated with the room goaf, the gate is installed on the observation pipe of the section extending outwards, and after paste filling is completed, the exhaust gap is formed between the gate and the room goaf. An exhaust gap is formed between the top of the paste and the top plate; according to the utility model, the paste filling roof contact rate can be improved while the exhaust in the chamber goaf is realized, the size of the space without roof contact in the chamber goaf is effectively reduced, the surrounding rock is controlled to be not eas
