description The invention relates to a slotting machine for coal seam gas extraction, in particular to a slotting machine for gas extraction. The technical problem to be solved is to provide the slotting machinewhich can be used for slotting a coal seam, and has a construction width greater than or equal to 1 m and a construction height greater than or equal to 0.3 m. The adopted technical scheme is as follows: the slotting machine comprises a main box body, a cutting cutterhead, a power system, a guide connector and a propelling system, the main box body is a cuboid matched with the shape of the cross section of a cutting seam, the cutting cutterhead is located in front of the main box body, and is connected with the main box body through a cutterhead support and connected with the power system driving the cutterhead support to rotate, and the front end of the cutterhead support is connected with a guide hole drill rod through the guide connector. The cutting cutterhead is a flat cylindrical cutterhead, and cutting teet
