2023101 · The phenomenon can occur in several environments, natural and artificial. In surface mining operations, blasting, bench clean-up and scaling can induce rock blocks detachment, compromising operators’ and operations’ safety. The installation of passive mitigation measures coupled with a specific design of the pit geometry can mitigate this risk.

The primary aim of every twenty-first century mining operation is to extract as much ore as possible in a safe and economical manner. Failure in mine excavation occurs when the shear stress acting on the rock is greater than the shear strength of the rock mass. The stability of rock slopes in open-pit mine and quarry operations is extremely important from …

201569 · Highwall concerns. A number of innovative solutions are available to address slope instability and rock-fall hazards. There are several geological hazards that are encountered during the life of a quarry or open pit mine. Most of these hazards are included in a mine’s Ground Control Plan (GCP). The GCP ensures adequate geotechnical …

2022418 · A critical step in planning an open-pit operation corresponds to the design of ramps required to access the different sectors and levels. This design is very complicated because the ramps affect the excavation’s shape, therefore, its economic value. Thus, planners generate contours to be used as reference for the design. These contours (or …

2024211 · Abstract This chapter reviews the main topics related to aggregate extraction from surface and underground methods. Although aggregate sources can be widely variable, the methods of extraction are very similar throughout the world, with crushed rocks mainly extracted from quarries (surface and underground mining) and sand and …
