This paper focuses on the sequencing and scheduling problem of open pit mining, with the allocation of loading equipment considering a medium-term horizon. This study considers the existence of a heterogeneous loading equipment fleet and two types of mineable material, namely ore or waste rock. For the mining of ore, the following requirements are taken under consideration: the mixture quality,...

In this study, the Lagrange element strength reduction method is used to explore slope stability and as an evaluation of underground mining end-slope coal in a rock-stability analysis. A numerical analysis model established herein using geological conditions for coordinated open pit with area Anjialing Open-Pit Mine Underground No. 2 Mine. Additionally, evolution law open-pit studied proposed s...

Mining activities can endanger the stability of hydraulic structures. Numerical modeling local scouring around hydrodynamic and circular bridge pile groups, due to action clear water conditions via non-cohesive sediment, was performed using a computational fluid dynamics (CFD) model, large eddy simulation (LES) turbulence van Rijn sedimentary model with FLOW-3D software. The groups were positio...

The increasing expansion of open-pit mining and the drastic transformations land use in Latin America have led to processes rural depopulation among traditional inhabitants, causing unsustainability life systems. In context profound, worldwide territorial environmental transformations, it is necessary anticipate change scenarios identify territories prone depopulation. objective this article de...

One of the most critical aspects open pit mining is dewatering and mine drainage systems. The NCP Open Pit Gold Mine located in Central Kalimantan. This study area has a range rainfall intensities durations from moderate to heavy. Good required manage runoff water reduce entering front loading. used daily intensity data 1994 2018. Using Mononobe Method, hydrological for this were evaluated by d...
