地质块段法是我们在进行储量计算时广泛采用的一种方法。采用这种方法计算倾斜矿体体积时,不能用矿体水平(或垂直)投影面积乘矿体真厚度。因为矿体的实际表面面积和水平面或垂直面投影图上的面积是不相符合的。因此,我们必须对投影图上面积的歪曲现象,给予适当的修正,以正确地求出矿体真正体积。修正的方法很简单,即当采用水平投影图计算体积时,要用垂直厚度来代替真正厚度;反之,用垂直(纵)投影图计算时,则以水平厚度代替真正厚
The Geological Block Method is a widely used method in our reserves calculations. When using this method to calculate the tilted orebody volume, the true thickness of the orebody can not be multiplied by the horizontal (or vertical) projected area of the orebody. Because the actual surface area of the ore body and the horizontal or vertical projection area does not match. Therefore, we must make appropriate corrections to the distortion of the area on the projection chart so as to find out the true volume of the ore body. The correction method is very simple, that is, when using the horizontal projection diagram to calculate the volume, the vertical thickness should be used to replace the real thickness; the other hand, the vertical (vertical) projection diagram, the horizontal thickness instead of the real thickness
