在储量计算工作中,矿石体重是一个重要参数。在实际工作中,由于多数矿种矿石体重的变化均比品位的变化幅度小得多,因而体重样品采集的数量也较少。进行储量计算时,一般采用算术平均法计算矿石的平均体重,就足以保证所求储量的精度。当然,矿石平均体重的计算,一般也要根据矿石类型、品级及储量级别等所划分的块段分别计算。天青石、重晶石等一些比重大、工业品位要求较高的矿种,由于矿石品位、体重变化
In the calculation of reserves, ore weight is an important parameter. In practice, the weight samples collected are less in most mineral ores because the weight changes are much smaller than the change in grade. The calculation of reserves, the general arithmetic average method to calculate the average weight of ore is sufficient to ensure the accuracy of the requested reserves. Of course, the average ore weight calculation, generally also according to the type of ore, grade and level of reserves, such as the division of the block were calculated. Celestite, barite and some other than the major, high grade industrial grade minerals, due to ore grade, weight change
