剥离量（overburden amount ）是指露天矿开采时需要剥去的废石量，计算单位为立方米。露天矿开采是把覆盖在矿体上部及其周围的浮土和围岩剥去，把废石运到排土场，从敞露的矿体上直接采掘矿石。
从而可以减少剥离量或增加采出矿石量，降低剥采比，提高矿山经济效益。
So, using the internal dumping could decrease the waste volume or increase the production, reduce the stripping ratio, and improve the economic benefit.
该边坡形状与传统的稳定性理论确定的边坡形状相比较，可在保证边坡稳定的前提下减少巨大的废石剥离量。
A great quantity of stripped waste rock can be reduced by the slope configuration determined by the proposed model, as compared with that determined with the traditional theory of slope stability.
阐述编制露天矿的各种开采计划的方法和步骤，以及其台阶划分、计划台阶顶底板的控制、编制剥离量和采矿量及其煤质指标等；
It expounds various mining methods and steps, including the bench demarcated, plan mining bench top and bottom floor, the coal and overburden amount of plan mining, and coal quality indicators.
