Le niveau d’influence des résultats d’une étude QA/QC sur l’exploitabilité d’un gisement peut être très élevé. Les études QA/QC visent à assurer la qualité et la fiabilité des données géologiques et géotechniques utilisées dans l’évaluation d’un gisement. Des résultats précis et fiables sont essentiels pour prendre des décisions éclairées concernant l’exploitation d’un gisement, notamment en […]

Gold deposits can be classified into several main types based on their geological characteristics and mode of formation: Magmatic-Hydrothermal Deposits Porphyry Deposits: Hydrothermal deposits associated with felsic to intermediate intrusions, characterized by low to medium gold grades but very high tonnages. Mineralization occurs in stockworks, fractures, faults or disseminated in the host rock. Epithermal Deposits: Formed […]

Russia is by far the greatest diamond mining nation in the world, having produced almost 37.32 million carats of diamonds in 2023. At that point, the production of roughly 25.1 and 16 million carats of diamonds placed Botswana and Canada in second and third place, respectively.

  Australia In terms of iron ore production by nation in 2022, Australia leads the pack. It is the world’s top producer of iron ore. Approximately 37.6% of global manufacturing is produced in the country. It yielded an astounding 900 million metric tonnes of iron ore in 2020. Brazil, its nearest competitor, is matched twice. […]

The SG-3, Kola Superdeep Borehole, or Zapoliarny borehole, named after the nearest town, or by its official name the Kola Superdeep Borehole Experimental Reference Well (SG-3), is a borehole drilled from May 24, 1970, to 1989 in the USSR, on the Kola Peninsula. This borehole is the deepest borehole in the world at 12,262m (actual […]

One of the important factors in designing a ramp or incline is the width. It is determined by the skip with the largest width. There are two general rules for determining this width: For a two-lane road, including curbs and drains, the minimum road width must be four times the width of the skip. For […]

Introduction Selection of blast pattern is a very important task in mining activities. The selection is made considering many effective factors; hence, there is a significant variation in the selected pattern from mine to mine. The most influential factors are annual mine production, required rock fragmentation, geological and geotechnical characteristics of the area, physico-mechanical properties […]

The compass is crucial in structural geology for measuring the orientation of geological structures such as bedding planes, joints, and metamorphic foliations. It helps geologists determine the strike and dip of these structures, which is essential for understanding the geometry and pattern of relative movement within the Earth’s crust. The compass is particularly important for […]
