摘要
崩矿步距是框定放出体三维结构参数中的重要一维 ,当分段高度进路间距已定时 ,对放矿效果有着决定性的影响。为寻求适应于 15m× 15m结构参数下的合理崩矿步距 ,本文对 15m段高 ,15m间距下的放矿步距与矿石损失贫化指标的关系 ,分别进行了物理模拟、计算机仿真、放出体工业试验及现场崩矿步距工业试验。
The independent advance of ore breaking is an important dimension in defining 3D structural parameters of drawing-off volume and has a decisive effect on ore drawing results when the sublevel height and access space are set.To find out a rational independent advance of ore breaking that suits to 15 m×15 m structural parameters,physical simulation,computer imitation,industrial tests of drawing-off volume and on-site independent advance of ore-breaking were made to obtain the relationship between the independent advance of ore drawing and ore dilution index at a 15 m sublevel height and a 15 m space.
