什么是SD法

What Is the SD Method

SD法是一种全新的矿产储量计算法和储量审定法。其理论是在分维几何学基础上发展并建立的SD动态分维几何学。两个基本概念是SD分数维和结构地质变量。由此衍生出一系列SD原理、方法和多个SD公式。SD法不仅可以根据不同勘查阶段、不同施工程度,多功能地计算任意划分细块的储量和变动工业指标后的储量,而且可以用SD精度法确定所计算的储量的可靠程度和工程控制程度。方法已在若干实际矿区进行了成功的应用。SD法已被国家正式确认,并予以全国推广。

The SD method is a new method for calculating mineral reserves and examining mineral reserves. The SD theory is based and developed on fraction dimension geometry.It mainly consists of the SD orebody fraction dimension theory and the structural geovariable theory,from which a series of SD elements, methods and expressions are derived.The SD method can not only calculate the reserves of random blocks and those of changed industry indexes based on different survey phases and different construction degrees,but also determine the credible degree of calculated reserves and the engineering control degree.The SD method has been successfully applied in some mines and has been formally affirmed and promoted throughout China.
