1) excavating height
开掘高度
1.
With the increase of the excavating height of footwall, the quantity of ores drawn in unit height is decreasing.
对应用无底柱分段崩落法开采矿床时的矿石损失过程进行了分析·在开采倾斜及缓倾斜矿体时,为改善因矿体倾角小而大量残留矿石的状况,可以通过采用开掘下盘部分岩石的方法,提高矿产资源的回收率·分析了矿体下盘倾角与下盘矿石残留量的关系,通过计算机模拟,得出了下盘岩石不同开掘高度与放出矿岩量的变化规律,随着开掘高度的增加,下盘矿石单位高度放出量相应减少,可按盈利总额最大原则确定出最佳开掘高度·在矿山生产实际中,下盘岩石最佳开掘高度随着矿产品价格和生产成本的波动而变化·研究结果表明:采用计算机模拟放矿过程,尤其是放矿控制方面,优于实验室物理模型放矿
