摘　　要：无底柱分段崩落采矿法存在损失贫化大和损失贫化难以控制的缺点。指出通过改变采矿方法可以克服无底柱分段崩落法的缺点,提出了用自然崩落法、大直径深孔采矿法、充填法及有底柱分段崩落阶段出矿方案替代无底柱分段崩落法的设想。Disadvantages of sublevel caving without sill pillar lie in high ore loss and dilution as well as difficult control of ore loss and dilution. The author points out that disadvantages of sublevel caving without sill pillar can be overcome through the change of mining method, and puts forward a conceive that block caving method, large -diameter deep -hole mining method, fill stoping method, and sublevel caving with sill pillar and level ore drawing plan are used to replace sublevel caving without sill pillar.
