Abstract
By analysis on gob-side entry-retaining technology in non-pillar recovery process,combined with geological conditions and rock characterization of 1232 and 1234 Work face in SongHe Mine.The practicing of Gob-side entry-retaining technology in two mining face of the same sections,analysis reveals that non-pillar recovery process can effectively control the gas explosion,pressure bump and other related incidents,controlling major accidents generated by raw coal pillar supporting roadway program.Ultimately relieve tension splice mining face,save excavation costs, improve coal recovery.关键词
