无底柱分段崩落法在劳服铁矿的适用性分析

Analysis on applicability of pillarless sublevel caving method in Laofu Iron Mine

针对劳服铁矿的具体地质情况和岩体条件,从无底柱分段崩落法的适用条件、矿岩可崩性评价等几个方面进行分析研究。分析结果显示,劳服铁矿采用无底柱分段崩落法进行地下开采是合理的,能够实现矿山的安全、高效开采。

Pillarless sublevel caving method is widely used in underground metal mines in China, but it needs some applicable conditions. Whether this method can be applied in Laofu Iron Mine still needs further analysis and demonstration. According to the specific geological situations and rock mass conditions in Laofu Iron Mine, the ap- plicability of pillarless sublevel caving method in this mine is analyzed from the aspects of the applicable conditions of the mining method as well as the cavability evaluation of rock mass and ore body. Through the comprehensive analy- sis, it can be concluded that pillarless sublevel caving method is suitable for Laofu Iron Mine in underground mining, which can realize the safety and efficient mining.
