Abstract：According to the status of more and more abnormal coal mining face layout in the boundary comer seam and the geological condition complicated area,during the 53lower08 fully mechanized coal mining face passing the main transport roadway "S" section,face shortening during mining method was used.With the rational production control approaches,face shortening during production was achieved.The Practice showed that,with the face shortening during mining method,the process of shrinking face was simplified,the construction period was shortened,material investment was reduced,and good economic benefits was achieved.The practice can provide references for the selection face width shortening mining mode for fully mechanized coal mining face.
