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。
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.
