摘要
高分段无底柱分段崩落法是实现大型无轨采矿设备和地下大规模开采的有效方法。本文结合酒钢镜铁山矿的开采技术条件,分析了开采工艺与大型采矿设备的匹配,论述了20m高分段的结构参数、采准与切割以及回采工作。
Sublevel caving mining of high sublevels is an effective method for realizing the application of large trackless mining equipment and the large capacity underground mining. In regard to the mining technological conditions of Jintieshan Iron Mine of Jiuquan Iron & Steel Co., the paper analysis the matching of mining technology and large mining equipment, discusses the structural parameters, preparatory work, cutting and extraction of 20m high subtevels and evaluates its application prospects.
