摘要: 为充分回收矿产资源,提高资源利用率,有效回收暂留盘区隔离矿柱是某大型铜矿必须考虑的一个重要问题。在保障首采区矿房、矿柱采场安全高效开采的同时,为了安全高效回收暂留盘区隔离矿柱,需要确定合理的盘区隔离矿柱采场结构参数。在综合分析该矿山矿床地质概况、矿山压力及开采现状的基础上,提出了3种采场结构初步方案,采用数值模拟方法对盘区隔离矿柱采场结构方案进行了优选,得到了采场处于最有利力学状态时的结构参数以及结构参数变化时采场的力学响应特征,分析结果可为盘区隔离矿柱安全高效开采提供技术支持。

Abstract: In order to take full advantage of the mineral resources and improve resource utilization, it is an important to be considered for a large copper mine to effectively recover temporary panel isolation pillar. Stope structure parameters of panel isolated pillar have been determined to be reasonably determined to safely and efficiently recover panel isolated pillar, at the same time stope and pillar stope’s safe and efficient have been sure in the first mining area. On the basis of comprehensively analyzing geological overview, mining pressure and mining situation of the mine, three stope structure preliminary plans were proposed by using numerical simulation method optimized stope parameters of panel isolated pillar. The stope could be in the most favorable mechanical state after obtained the structural parameters and mechanical response characteristics of the stope with the changing structural parameters. The results could provide technical support for safely and efficiently mining panel isolated pillar.
