无底柱分段崩落采矿法是否适用于松软破碎矿体,一直是采矿界争论的焦点。武汉钢铁(集团)矿业有限责任公司所属地下矿山采用该采矿法的生产实践表明,矿岩条件复杂的矿山,只要因矿制宜、灵活应用无底柱分段崩落采矿法的开采原则,不断改进与完善结构参数,采用一些适应自身矿岩条件的生产工艺技术,同样能达到硬岩矿体的开采效果。

Whether the sill-free sublevel caving mining method is suitable to break and broken orebody has been being discussed for a long time.The practice of sill-free sublevel caving mining method in iron mine,Wuhan Iron and Steel(Group) Corp.shows that a satisfactory mining efficiency can be expected under complicated if the structure parameters is adjusted and optimized according to the mining conditions.
