Abstract: According to the status of more and more abnormal coal mining face layout in the boundary corner seam and the geological condition complicated area，during the 53next08 fully mechanized coal mining face through the tape transport lane "S" section, a trail of mining and shortening method was conducted ，With the rational production control organized,production and shrinkage was achieved, which solved the influence of irregular surface shrinkage. The Practice showed that the fully mechanized coal mining face with the face width shortening mining，Adopts mining and shortening method, simplify the process of shrinking face, shorten the construction period, reduce material investment, and has achieved good economic benefits.The practices could provide the reference to the selection of the face width shortening mining mode for the fully mechanized coal mining face.
