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 […]

Types of Gold Deposits
MarcialGold 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 […]
Top 10 diamond producers in the world in 2023 (in million carats)
MarcialRussia 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.
Top 10 Iron producers in the world in 2023
MarcialAustralia 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. […]
Drilling History: The Kola Superdeep Borehole
MarcialThe 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 […]
Mine design: slope of ramps or inclines
MarcialOne 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 […]
Flyrock after blasting: Effects and mitigation strategies
MarcialIntroduction 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 geological compass and its importance in geology
MarcialThe 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 […]
The pipeline blasting
MarcialWhat Is Trench Blasting & When Is It Necessary? Trench blasting, also known as pipeline blasting, is a process of using controlled explosives to facilitate the excavation of trench and pipeline projects in rock formations. Drilling holes into the rock formation and inserting explosives there completes this operation. With less work, trenches and pipelines may […]
