bench height

基本解釋

The paper presents the functional relationship between transport work of ore and rock handling and bench height in open-pits.
文章給出了露天鑛採出鑛巖運(yùn)輸功與臺(tái)堦高度的函數(shù)關(guān)系。
The research result showed that the average transport work content of ore and rock in open-pit decreases as bench height increasing.
研究結(jié)果表明，隨著臺(tái)堦高度的增加，採出鑛巖平均運(yùn)輸功含量呈下降趨勢(shì)。
Bench height increasing is beneficial to reducing mining cost.
增加臺(tái)堦高度對(duì)於降低採鑛成本是有益的。
