Investigation on flow field characteristics in an open-pit coal mine [PDF]
Abstract In this paper, the atmospheric flow field characteristics in a deep open-pit mine are investigated numerically and theoretically. A theoretical model on the recirculation length based on the energy equation is used, a total variation diminishing (TVD) difference scheme with second order accuracy is used to solve the NS equations with a

Landslide mechanism and stability of an open-pit slope: The Manglai open-pit coal mine
Abstract A clear understanding of landslide mechanisms and stability analyses is of great significance for landslide monitoring, prediction, and control. A large-scale end wall landslide occurred on August 7–20, 2020, in the Manglai open-pit coal mine, China.

Can you take the heat? – Geothermal energy in mining [PDF]
In 2013, there are less than 20 documented examples of operational geothermal systems on mine sites worldwide. This is surprising, since on remote mine sites, where fuels may have to be shipped in over great distances, heating and cooling from low ...

Study on Optimization of Coal Truck Flow in Open‐Pit Mine [PDF]
A semicontinuous process system consisting of a single‐bucket excavator, truck, crushing station, and belt conveyor is the main coal mining process system of a large‐scale hard coal open‐pit mine. Through analyzing the coal mining production process, the key issues of coal mining truck flow optimization are obtained.

Pollutant emission from fires at open-pit coal mines
Abstract Existing coal mining technologies are associated with significant pollution of the natural environment, especially atmospheric air. On top of this, in the event of an emergency related to the spontaneous combustion of coal, this negative impact significantly increases.

Unravelling the relative contributions of climate change and ground disturbance to subsurface temperature perturbations: Case studies from Tyneside, UK [PDF]
When assessing subsurface urban heat islands (UHIs) it is important to distinguish between localized effects of land-use change and the impacts of global climate change. However, few investigations have successfully unraveled the two influences.
