Zusammenfassung:The invention provides a rapid mining method for an underground coal mine thin coal seam working face, and belongs to the technical field of underground mining of underground coal mines, the method can realize lateral rapid cutting feed and rapid back-and-forth running coal cutting of the end coal wall of the working face, and compared with an end beveling cutting feed and reverse coal cutting mode of a thin coal seam fully mechanized working face at the present stage, the method has the advantages that the mining efficiency is greatly improved; the back-and-forth idling operation procedure of the coal mining equipment part is canceled, and meanwhile, the auxiliary operation time in the coal cutting process is greatly shortened, so that the single cycle operation time of the coal mining working face is shortened, and the mining efficiency of the thin coal seam working face is improved; in the rapid coal cutting process of compact coal mining equipment, rapid following pushing of a short scraper conveyor and r
