Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -One of the most important viewpoints of data mining concerning the analysis of a large amount of data and samples with different characteristics includes clustering which is associated with methods and techniques that have frequently been applied in different fields of researches. A well-known algorithm of clustering is K-means by which the data are divided into K classes based upon a distance criterion. In this study, the K-means method applies for data classification derived from exploration boreholes and surface sampling in the Parkam deposit. The results derived based on the case of borehole data showed that the increasing Cu grade values resulted in a significant increase in Mo grades, a significant decrease in Pb grades followed by an increase, and the Zn grades varying comparable to Pb. With regards to the relationships between these elements it could be concluded that the meteoric waters promoted the mobilization of Pb and Zn from the potassic to the phyllic zone but the meteoric waters were not effective enough to cause the mobilization of Cu, and this element together with Mo remained immobile. Finally, equation of Cu grade estimation is also presented for surface data. 60 pp. Englisch.…

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - En los últimos años, debido a la gran dependencia de los proyectos mineros de la determinación precisa del tonelaje de los materiales minerales, se han desarrollado diversos métodos para estimar la ley, como los métodos geométricos basados en la distancia y la geoestadística. Cada método tiene limitaciones y desventajas que afectan a la exactitud de la estimación. Uno de los nuevos métodos es la estimación de la ley utilizando la agrupación. Los métodos de análisis de conglomerados se utilizan ampliamente en las ciencias de la tierra. El método de agrupación de conglomerados se utiliza para clasificar los datos geoquímicos. El análisis de conglomerados conecta las observaciones entre sí, que juntas tienen muchas similitudes, y luego las observaciones consecutivas las conectan con las más similares a las observaciones anteriores.En este libro, pretendemos examinar los siguientes métodos:1- Correlación2- Análisis jerárquico3- K-Means4- Análisis de regresión5- PCA (Análisis de Componentes Principales)6- DA (Análisis Discriminatorio).…

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - exploratory surveys (geochemical and geophysical) are important and basic steps in the mineral exploration; The importance of this stage includes several reasons that are intertwined; First, the precision and accuracy of the measured data compared to the investigated community, whether they are representative of it or not, and can the data be used as representative of the community in future studies Second, the density of exploratory surveys that is directly related to management resources (Time, cost, human and equipment); Third, the exact location of the exploration, which must be purposefully selected, so that optimal results can be obtained by spending the least amount of resources.…
