摘要: 司家营常峪铁矿为控制采矿引起的地表岩移,采用地下开采充填采矿法采矿。在确保安全的基础上,选取合理的矿块结构参数,对矿山设计和建设尤为重要。通过应用FLAC3D软件对不同尺寸的矿块结构进行了数值模拟,得出了矿山充填法采矿矿块结构最优参数,为矿山设计及开发建设提供了依据。  

关键词: 充填法采矿, 矿块结构, 优化

Abstract: To control the surface movement caused by mining,the backfill mining method was adopted for underground mining in Sijiaying Changyu iron mine.On the basis of safety production,selecting appropriate parameters of ore block structure is particularly important for the design and construction of the mine.Through the application of FLAC3D to simulating different sizes of ore block structures,the block structure optimal parameters of filling mining method were obtained,which provided the basis to the design and development of mine.

Key words: Mining with backfill, Ore block structure, Optimization
