The coal pillar stoping face uses local ventilators, air is pressed from the intake roadway into the coal pillar face through flexible air pipes, and the air is returned via the return roadway. During stoping of an upper section, major factures are given to a main roof over a coal wall by pre-blasting, , the basic roof breaks at this position after stoping, and thus pressure increase in close-to-gob areas caused by rotation of the main roof is decreased. In addition, a filled wall which is formed by means of filling and the like isolates an upper section gob area and a lower section coal pillar stoping face, and thus roof fall and side spanning accidents caused are decreased.
