摘要
杨山铁矿为露天与地下联合开采矿山,开采技术条件复杂。为确保地下开采作业的安全,对矿山设计拟采用的分段空场嗣后充填法中顶底柱厚度、间柱宽度、阶段高度及矿块段宽度等参数设置不同水平值并进行方案正交设计,正交方案结合FLAC3D数值模拟软件分析数据进行优化以获取合理的采场结构参数。分析结果有利于指导杨山铁矿组织生产作业,对类似矿山具有一定的参考价值和理论意义。
Yang Shan Iron Mine is an open-air and underground combined mining with complex mining conditions. To ensure the safety of underground mining operations, the parameters of the top and bottom pillar thickness, the column width, the digging height and the ore block width etc in sublevel open stopping subsequent filling can be set up different and made orthogonal design scheme. The orthogonal scheme combines FLAC3D numerical simulation software to analyze the data and optimize so as to obtain reasonable stope structure parameters. The analysis is useful to guide the organization of production for Yang Shan Iron Mine which will have a certain reference value and theoretical significance.
