尖山铁矿无底柱分段崩落法结构参数研究

摘要

通过放矿理论计算式归纳和室内放矿试验综合研究,得到尖山铁矿无底柱分段崩落法合理的结构参数,为确保矿山生产能力、降低损失贫化和减小采切比奠定了基础,同时为初步设计及施工图提供了依据.%According to the comprehensive study on the formula of drawing theory and indoor drawing test, the reasonable stope structure parameters of non-pillar sublevel caving mining method in Jianshan Iron Mine were obtained. It guarantees the production of mine, and reduces the loss and dilution index. Meanwhile, it provides the proof for preliminary design and construction.
