Understanding orebodies with hyperspectral images - Nature
2022年9月12日 · One way to anticipate technical and environmental challenges during raw material exploitation is through detailed understanding of orebody mineralogy. Various techniques can distinguish minerals...
Ore Body - an overview | ScienceDirect Topics
Generally, an ore body is an accumulation of a solid and fairly continuous mass of ore with gangue, distinctly distinguishable by form and character from the enclosing host rocks. An ore deposit might include single or several ore bodies.
Oblique distribution patterns and the underlying mechanical …
2024年2月26日 · This paper uses the northeastern Yunnan Ge-rich Pb–Zn ore concentration area in the Sichuan–Yunnan–Guizhou metallogenic area as an example to analyse and demonstrate the oblique distribution...
Interaction between karst terrain and bauxites: evidence from ... - Nature
2017年9月19日 · Here we discuss how the relation affects the karst and bauxite evolution through analyzing distributions of orebody parameters from 9,007 exploration wells (434 orebodies) in western Guangxi ...
Ore Body, Shapes and Occurrence of | SpringerLink
2022年12月27日 · The ore body has a certain shape, occurrence, and scale. The rocks without economic significance around the ore body are the surrounding rocks. The boundaries between the ore body and the surrounding rocks are clear under some geological conditions, while they are gradually transitional under other conditions.
Orebody vertical structure and implications for ore-forming processes ...
2011年8月1日 · The orebody vertical structure with high-level evenness may support a simplification of exploration sampling strategy, i.e., sampling the wells as a whole instead of meter by meter. The results also demonstrate that the higher karstic depressions are likely to have uniform oxidizing environments, inducing a marked increase in Fe 2 O 3 content ...
Ore Body Knowledge - SpringerLink
2019年12月15日 · Overall, ore characterization is the quantification of physical and chemical properties of ores in an ore body. This information forms the basis for any geometallurgical approach. Table 2.1 lists the possible ore characterization investigations for a …
Implicit modeling of complex orebody with constraints of geological ...
2019年11月1日 · To dynamically update the shape of orebody according to the knowledge of a structural geologist's insight, an approach of orebody implicit modeling from raw drillhole data using the generalized radial basis function interpolant was presented. A variety of constraint rules, including geology trend line, geology constraint line, geology trend ...
Orebody Modeling from Non-Parallel Cross Sections with Geometry …
2019年4月12日 · In this paper, we present an improved approach to the surface reconstruction of orebody from sets of interpreted cross sections that allows for shape control with geometry constraints. The soft and hard constraint rules based on adaptive sampling are proposed.
Types of orebodies on the basis of the occurrence depth and …
2012年11月30日 · It is established that natural stress fields in the same type geological and tectonic structures are similar in mining regions worldwide. The author has distinguished four geomedium models differentiating the change of the rock stress state with increase in the rock occurrence depth.
