品位-储量曲线能够反映一定的边界品位以上的矿石量有多少,这可为制定矿山开采计划提供非常有用的资料.但是在计算中需要注意一些原则,以免发生严重误差.有两种确定曲线的方法.第一种方法是不划分矿块,而从全部资料中求得.这时,曲线可能有代表性,并可正确地反映某一品位指标以上的矿石储量,但是不能表示富矿在哪里,也不能指出矿体与围岩的界线.按照第二种方法,曲线是根据构成矿体的各个
The grade-reserve curve reflects how much of the ore is above a certain boundary grade, which can provide very useful information for the development of a mining plan, but some principles need to be considered in the calculation to avoid serious errors. There are two deterministic curves Method.The first method is not divided into nuggets, and obtained from all the data.At this time, the curve may be representative, and can accurately reflect the ore grade above a certain grade index, but can not indicate where the rich ore, Nor can we point out the boundary between ore body and surrounding rock.According to the second method, the curve is based on each
