摘　　要：无底柱分段崩落法按分段连续回采,当回采面积足够大时,完全可以利用第一分段的连续采空区诱导上部矿岩安全冒落。北洺河铁矿应用这一技术形成诱导冒落与强制崩落相结合的无底柱高效采矿工艺,创造了投产19个月达产的国内最好纪录。In sublevel caving mining without sill pillar, the mining progresses continuously by sublevels. Therefore, when the area of exposed roof is sufficiently large at the first sublevel in sublevel caving, the ore in upper sublevels can be induced to cave in a safe way making use of the mined - out area at first sublevel. The application of this induced caving technique has formed a high - efficiency non - sublevel pillar mining technique based on the combination of induced caving and forced caving in the Beiminghe Iron Mine, and results in a China＇s short - time record that the deigned production capacity of the mine was reached after going into production for one year and seven months.
