The invention discloses a vertical cutter feeding type mining process suitable for a thin coal seam fully mechanized coal mining face and belongs to the technical field of coal mining. The problems that a conventional fully mechanized coal mining unit performs inclined cutting cutter feeding, triangular coal cutting and other tedious procedures during thin coal seam mining, consequently, efficiency is low, and a coal plough unit is poor in mining process device adaptability are solved. Vertical cutter feeding serves as a cutter feeding manner; and an intercepting and cutting device, a scraperconveyer, a hydraulic support, a crossheading transferring device, a centralized control center and the like are included. The intercepting and cutting device installed on the scraper conveyer is cutinto the coal wall in a vertical intercepting and cutting manner at the two end heads of a roadway, and vertical cutter feeding is completed; and then the intercepting and cutting device is pulled bya chain traction mechanism to complete intercepting and cutting the coal wall in the length direction of the whole coal mining face. According to the vertical cutter feeding type mining process suitable for the thin coal seam fully mechanized coal mining face, the auxiliary coal cutting time is shortened, the labor intensity of a worker is lowered, the mining efficiency of the fully mechanized coal mining face is improved, the coal cutting procedure is simplified, and a good foundation is laid for later thin coal seam coal mining faces to achieve intelligent mining.
