摘要
在小汪沟铁矿216m水平分段边缘矿体中,由于矿体形态和周围工程的约束,采用有底柱分段崩落法回收该部位矿体。通过对回采工艺的优化设计和出矿效果的定量评估,证明有底柱分段崩落法是一种行之有效的边缘矿体回采方法。
Because of the restriction of ore body shape and the surrounding projects,sublevel caving with sill pillar method was used to mine the edge ore body of 216m level in Xiaowanggou iron mine. Through optimum design of extracting technology and quantitative assessment about drawing efficiency,sublevel caving with sill pillar was proved to be an effective way in mining edge ore.
