Abstract: Abstract: According to the problem of reasonable coal pillar width and the safe remove of powered support at ending stage of fully-mechanized face in shallow seam，theory analysis and practice method was adapted to research the coal face of Zhuanlongwan NO.23103. The results show that the influence scope of advancing abutment pressure at ending stage of NO.23103 coal face was about 19~20 meters, the width of stress limit equilibrium zone of protective pillar was 4.86 meters. The research results can be applied to NO.23103 coal face in which the protective pillar of the entries between the recovery room was 20 meters, the yield position was determined at 5 meters. No need to take any measures at yield position through taking practice method and theory analysis, the coal face just need to keep continuing to move forward which realizing a fast coal face perforation and a safe working-face removing.
