Optimization of parameters of shovel-truck systems at open-pit coal mines

Mining Industry Journal (Gornay Promishlennost), 2022
owerful shovel-truck systems (STSs) are widely used to perform overburden operations in open-pit mines. One of the main STS problems is the low level of its operation quality.

Study on Dust Distribution Law in Open-Pit Coal Mines Based on Depth Variation

Atmosphere
This study examines the influence mechanism of mining depth evolution on dust distribution, using the An Tai Bao open-pit coal mine as the research subject. A spatial coordinate system of the mining area was established utilizing a GIS positioning system,

Preparation of topsoil alternatives for open-pit coal mines in the Hulunbuir grassland area, China

Applied Soil Ecology, 2020
To solve topsoil shortages caused by the thinner topsoil layer resulting from open-pit land reclamation in northwestern Chinese grassland areas, the overlying rock and soil layer of an open-pit coal mine in Inner Mongolia was used as a matrix, and ...

Preparation and performance evaluation of an efficient microbial dust suppressant for dust control in disturbed areas of blast piles in open-pit coal mines.

Journal of Environmental Management
Open-pit coal mining creates large rock piles as a result of removing overlying strata. When disturbed by loading operations and wind, these rock piles release considerable dust, leading to significant environmental pollution.
