Epidemiological studies indicate that living in proximity to coal mines is correlated with numerous diseases including cancer, and that exposure to PM10 and PM2.5 components could be associated with this phenomenon. However, the understanding of the mechanisms by which PM exerts its adverse effects is still incomplete and comes mainly from studies in occupationally exposed populations. The aims...
one of the main concerns of the mining industry is to determine ultimate pit limits. final pit is a collection of blocks, which can be removed with maximum profit while following restrictions on the slope of the mine’s walls. the size, location and final shape of an open-pit are very important in designing the location of waste dumps, stockpiles, processing plants, access roads and other surfac...
One of the main stages in design mineral development process is solution finding optimal open pit problem. It necessary to take into account spatial distribution components and allowable slope angles sides during solving this The basis for performing calculations optimize extraction reserves a digital block model deposit. larger more accurate ore deposit requires computationally complex calcula...
During the production of open-pit mines, stability slopes can be affected by various factors such as structural surfaces, blasting vibrations, and mining areas. In this study, researchers focused on slope mine at Yinshan employed UAV mapping technology to conduct an on-site geological engineering investigation. Information yield, trace length, spacing, density surface south was obtained. The al...
Almost all post exploitation open pit mines in the world are shaped as a final reservoir intended to be filled with water. In Europe, creation of water lakes is most common way reclaiming mines. The safety and security mine one priorities regions. One main hazards identified slope stability lake banks. To develop reliability methodology for assessing long-term flooded mines, large-scale numeric...
