摘　　要：薄煤层开采的特殊性造成薄煤层长壁机械化开采发展缓慢,目前主要以炮采和机采为主。国内外薄煤层机械化开采较成熟的工艺主要有长壁式开采、螺旋钻机开采、连续采煤机房柱式开采及急倾斜煤层钢丝锯开采。The particularity of thin coal seam makes the thin coal seam mining with longwall and mechanization slowly develop, the blasting and mechanized mining is main nowadays. More mature technique of thin coal seam mechanized mining at home and abroad mainly includes ： longwall mining, spiral drill mining, continuous miner room- and- pillar mining, steel saw mining in steep seam.
