摘要: 某矿在实施大直径深孔阶段空场法开采的过程中,根据矿体的赋存条件、开采经济上的可行性和生产管理等情况,采取垂直矿体走向和沿矿体走向两种布置矿块形式。在矿岩力学性质研究的基础上,运用有限差分软件FLAC3D对该矿大直径深孔阶段空场法采场结构参数进行数值模拟研究,以确定矿块、矿房、矿柱等参数。

Abstract: During the process of implement of large-diameter deep-hole stage open stoping method of a mine, according to the occurrence condition of ore body, feasibility of mining economic, production management and other situation, vertical ore body to the layout of the mine block and along the ore body to layout of the mine block were adopted.On the basis of rock mechanical properties study, numerical simulation was done on stope structural parameters of large-diameter deep-hole stage open stoping method of this mine by FLAC3D, and the parameters of ore block, ore room, pillar were determined.

Key words: Large-diameter deep-hole stage open stoping method, Pillar parameters, Numerical simulation
