    In Songshan Coal Mine, Some adverse conditions were overcome in "three soft" coal seam, such as large pressure in coal seams, to pressure fast. Through the research and practice of withdraw technology at the fully mechanized coal face, the withdraw period of 2201 fully mechanized coal face was greatly shortened. The safe, fast and efficient retracement purpose at the fully mechanized coal face was realized.
