摘　　要：北洺河铁矿用大结构参数强制崩落与诱导冒落相结合的无底柱高效率采矿方法开采,采场内底板残留矿量较多,需在围岩里设置特殊工程加以回采。本文采用在底板围岩里加密进路的技术措施回收底板残留矿量,并根据绘制的放出体、残留体形态与矿岩稳定特点,分析回收进路的合理位置与回采方法等问题。The main mining area in Beiminghe iron mine is mining with the method of non-pillar sublevel caving which large structure parameter combined with induced caving.To fully recover the residual ores,there needs to set supernumerary a recovery drift between every two normal stoping drifts.This paper studied and analyzed several problems according to the characteristics of loose body,the shape of residual body in floor and the feature of ore-rock stability,such as the rational location of recovery drifts,mining method and so on.
