一种不平行断面的储量估算方法

Reserves estimation method of transecting section

鉴于现行法定的不平行断面法——即普罗科斯菲耶夫法因存在理论依据不充分,该方法的准确度差。该文在对普罗科斯菲耶夫法剖析的基础上,系统地介绍了拟建方法的基本思路、基本原理和包括斜交剖面的块段面积重心求解、斜交剖面投影面的块段面积计算、块段厚度确定、块段体积计算和方法准确度等内容的方法建立过程。从拟建方法准确度显示,该方法误差为零,从另一方面佐证了本方法的理论依据;同时也表明,该方法使用简捷,可作为一种新方法推广应用。

In view of method of transecting section （the method of Prokofiev） exitting absence of theoretic basis,it has low accuracy. Basing on research and analysis the method of Prokofiev, this paper presents a way which is about basic thinking and principle of designing;solving block area of oblique section center of gravitylcalculating block area of oblique section projection planel determinating block area thickness^computing volume of block and the accuracy of method.From the way,we found error is zero.On the other hand,it shows the feasibility of the method.This method is simple to use,it can extend as a new way for our use.
