摘要

Gy公式的应用适用于在采样方案的任何阶段和采样前计算基本采样误差(FSE)的方差。然而，由于使用一般因素来估计矿石特征，该公式可能不准确。为了在不使用Gy因子的情况下计算基本采样误差和最小代表性样本质量，有实验来校准采样参数，即:异质性检验(HT);采样树实验(STE)和无分离分析(SFA)。本文叙述了三种铝土矿标定方法的实验过程，并说明了它们之间的相关性。

The application of sampling theory in bauxite protocols

The applications of Gy's formula are appropriate for calculating variances of the fundamental sampling error (FSE) at any stage of the sampling protocol and before samples are collected as well. However, the formula can be inaccurate because general factors are used to estimate the ore characteristic. In order to allow the calculation of fundamental sampling error and the minimum representative sample masses without using Gy's factors, there are experiments to calibrate the sampling parameters, namely: the heterogeneity test (HT); the sampling tree experiment (STE) and the segregation free analysis (SFA). The present work describes the experimental procedure for the three calibration methods using bauxite and shows the correlation between them.

期刊介绍： REM – International Engineering Journal (antigua REM – Revista Escola de Minas) es la primera revista técnica de Sudamérica. Fue fundada en enero de 1936 por los estudiantes de la Escuela de Minas de Ouro Preto y desde entonces se ha especializado en la publicación de artículos en las áreas de la Ingeniería Civil, Geología, Metalurgia y Materiales y, Minería y Mecánica y Energía. Su objetivo es servir como un medio de publicación para los trabajos técnicos y científicos originales de investigadores nacionales y extranjeros en esas áreas. Contribuciones originales (artículos y cartas) son aceptadas. Artículos de revisión dependen de la invitación y/o análisis de los Editores. El envío de artículos para su publicación implica que el trabajo no ha sido publicado previamente, que no está siendo presentado para su publicación en otra revista y no se publicará en otro lugar, en la misma forma, sin el permiso, por escrito, de los Editores/Autores.
