摘要

层状矿床的地质建模可能变得非常复杂，通常需要使用小厚度的地质包裹层，并需要使用子块(基于笛卡尔坐标)来产生连贯的块体模型。然而，矿床形成后的地质事件(褶皱、断层等)会改变某些属性的空间连续性方向，导致同一标高的不同形成时代(层状矿床)样品的混合。该研究为地层等级不同的矿床结合不同来源的样品提供了一种解决方案。该解决方案是通过积累磷矿中p2o5的厚度获得的二维估计(与传统的三维统计分析相比)。

The effect of accumulation in 2D estimates in phosphatic ore

The geological modeling of stratiform deposits can become very complex, often making use of geological envelopes of small thickness and requiring the use of subblocks (based on Cartesian coordinates) to produce a coherent block model. However, geological events after the formation of the deposit (folds, faults, etc.) can change the direction of spatial continuity of certain attributes, with the mixing of samples belonging to different formation eras (in the case of stratiform deposits) in the same elevation. This study presents a solution for deposits with stratigraphic grades combined with samples of different origins. The solution is a two-dimensional estimate obtained by accumulating the thicknesses of P 2 O 5 in a phosphate deposit (as compared to traditional statistical analysis in three dimensions).

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.
