Management of Excess Mined-Out Space of Quarry Fields of Coal Open Pit Mines [PDF]
E3S Web of Conferences, 2021 Regardless of the applied technology of coal mining, a technogenic resource of the open pit is formed – excess mined-out space. Excessive mined-out space should be understood as a part of the internal space of a pit that is not used for placing ...

, 2021 Open pit mining method is one of the surface mining methods that has a traditional cone-shaped excavation and is usually employed to exploit a near-surface, nonselective and low-grade zones deposits. It often results in high productivity and requires large capital investments, low operating costs, and good safety conditions.

Coal flow detection system for belt conveyor based on dual lidar
Gong-kuang zidonghua, 2023 Due to the presence of stacking angles during the transportation of coal flow by belt conveyors, the shape of the coal flow is approximately triangular. It can easily lead to blind spots in detection. In order to solve this problem, a coal flow detection

Justification of the Relationship of Production Capacity and the Parameters of the Blocks at Surface Mining of Existing Kuzbass Quarry Fields [PDF]
E3S Web of Conferences, 2019 Today, up to two-thirds of the world’s minerals are mined in an open, more economical way. However, at the same time, billions of tons of overburden are extracted, which are piled in the dumps, where they are polluted, lose their value and, in addition ...

Efficient simulation for an open-pit mine
Simulation Modelling Practice and Theory, 2022 This paper presents an approach towards computationally efficient discrete-event-simulation designed to take advantage of high-performance computing architecture. We demonstrate how computational efficiency combined with large computing capacity enables quantification and mapping of stochastic system performance across a computationally challenging ...
