在储量计算中,当采用平行断面法计算矿块体积时,其计算方法常用的有两种:1.直接利用几何形体公式计算矿块体积,即:V=(S_1+S_2)/2·L(1)(2)V=(S_1·L)/3(3)V=(S_1·L)/2(4)又规定:S_1与S_2相差不超过40%时用式(1);相差超过40%时用式(2);当S_1或S_2为O时,矿体作圆锥形尖灭用式(3);矿体作楔形尖灭时用式(4)。最常见的情况是有两个断面对应求算矿块体积,其计算手续比较复杂,因为在选择公式之前,必须先比较一下它们相差是否超过40%,
In the calculation of reserves, there are two commonly used methods for calculating the volume of the ore block when using the parallel section method: 1. Calculate the volume of the ore block directly using the geometric body formula, that is: V = (S_1 + S_2) / 2 · L (1) (2) V = (S_1 · L) / 3 (3) V = (S_1 · L) / 2 (4) It is further stipulated that the difference between S_1 and S_2 is less than 40% 40% when using formula (2); when S_1 or S_2 is O, the orebody is used as conical tip extinction formula (3); The most common situation is that there are two sections corresponding to calculating the volume of the ore block, the calculation procedure is more complicated, because before choosing the formula, we must compare whether they are more than 40%
