Abstract: Stress on horizontal pillar under backfill is more concentrated,the mining sequence and mining methods play an important role to control the stablity of horizontal pillar and mining area.To study the horizontal pillar mining sequence,adopt the pillar and horizontal pillar synergetic mining sequence.Analyzing feasible horizontal pillar mining method,select the safe and efficient mining method.Through adopting the rational mining sequence and mining methods to ensure the stbablity in the process of horizontal pillar mining,exploit the horizontal pillar resources in the maximum degree.
