摘要
针对三山岛金矿采充工作受多方面影响,易造成矿区采充不平衡的现象,提出运用平衡动态分析理论,建立采充平衡动态模型,确定采充平衡协调发展水平及影响矿区采充平衡关系的主要因素,保障井下持续、均衡、高效生产。实践表明,通过采充动态平衡分析模型的应用,三山岛金矿各采场充填回填率高达95%,生产规模达到1 700t/d,有效促进了矿山的快速发展。
The mining-filling work is influenced by many factors,which tends to cause loss of equilibrium in mining and filling.The analytical theory of dynamic equilibrium was proposed to build the model of dynamic equilibrium between mining and filling and ensure the coordinating development level about mining-filling equilibrium.The principal factors affecting the equalized relationship between mining and filling were examined to ensure the underground continuous,balanced and efficient production.The experiment shows that it can achieve the average backfill filling rate of up to 95% and the production of 1 700t/d,which effectively promote the development of the mine.
