摘要
指出,目前我国推行的矿产工业指标中,无论对矿化不均匀还是较均匀的矿床执行三项品位指标,均有利于正确评价矿床的工业价值。认为,矿床最低工业品位虽不是一项圈定矿体、计算储量的直接指标,但却是决定矿床能否被工业利用的关键品位。建议,以矿床最低工业品位为界,在能利用储量(表内储量)一类中划分出应盈利的能利用储量(应盈利的表内储量)和尚难盈利的能利用储量(尚难盈利的表内储量)两个亚类。
It is suggested that using three grade indexs in the industrial factors for ores which are.popularized in China isfavourable to correctly evaluate the industrial value of deposits,not only for homogeneously mineralizing deposits,butalso for unhomogeneously mineralizing deposits.Although MIGD is not a direct index to block out oer-bodies andcalculate resources,it is a key factor to determine a deposit which be mined or nor.We suggest that taking MIGD asthe standard,usable resource can be divided into two subtypes:one is profitably usable resource and the other is unprofitablyusable resource.
