| 摘 要： | 通过理论推导，指出在平行断面法资源／储量估算中，在块段相邻剖面不具有相等对应边的情况下，梯形体公式只是一个近似估算公式，存在着一定的误差。而截面圆锥体公式则是一个精确的通用公式，其使用不受相对面积差大小的限制。因此，在这种情况下，建议放弃使用梯形体公式，而统一使用截面圆锥体公式。

| Abstract: | Through theoretical derivation, it is pointed out that in resources / reserves estimation by using me parallel cross-section method, when block adjacent sections do not have the same sides, the trapezoid body is just a approximate formula to estimate resource/reserve, and there is a certain degree of error. The cross - section cone is ageneral formula with good precision. Its use is relatively free from restrictions on different sizes of squares. There- fore, it is proposed to limit the use of trapezoid body formula, and use a unified formula of cross-section cone. |
