| 摘 要： | 露天开采矿山边坡外矿量是指由于露天开采安全边坡角限制不能采出的矿量,边坡外矿量包括勘探线剖面上的边坡外矿量和纵剖面上的边坡外矿量。勘探线剖面上的边坡外矿量可在计算剖面矿体面积时直接扣除;纵剖面上的边坡外矿量可根据剖面图形特点采用锥形体体积公式V=1/3×S×h/tgα或斜楔形体体积公式V=1/6×S×h/tgα×(2+m1/m2)估算体积后扣除。

| Abstract: | Be restricted by the angle of opencast mining safety slope,the ore quantity during opencast mining are the can not mined ore quantity,which are composed of the ore quantity of outside slope on longitudinal profile and exploratory line profile.We could deduct the ore quantity on the exploratory line profile while calculating orebody acreage,and deduct the ore quantity on longitudinal profile after estimating the volume with the formula of V=1/3×S×h/tgα（taper）and V=1/6×S×h/tgα×（2＋m1/m2）（wedge） according to the profiles characteristics. |
