摘要

评价采矿项目的风险与估计错误的可能性直接有关，由于估计是根据抽样结果作出的，这项活动必须以谨慎和有计划的方式进行，以防止在开始作业时出现意外。为了验证为矿物加工研究选择的钻孔样品的代表性，地质资源评价小组提出了一种基于利用统计分析的方法，该方法除了考虑样品在矿床中的空间分布外，还评估它们是否代表所调查的种群。有了这些数据，地质学家就能对样品的代表性进行快速分析。

Methodology for selection of samples from borehole probe for technological characterization of iron ore

The risks in the evaluation of mining projects are directly related to the probability of errors in the estimates, and, as the estimates are based on sampling results, this activity must be performed in a careful and planned way, to prevent surprises at the beginning of operation. To validate the representativeness of the borehole samples selected for the mineral processing studies, the geological resources evaluation team proposed a methodology based on the utilization of statistical analyses that, beyond considering the spatial distribution of the samples in the deposit, also assessed if they are representative of the populations under investigation. With this data, the geologist is able to make a fast analysis of the sampling’s representativeness.

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.
