The process of open-pit mining often produces a significant amount of waste material, including tailings, which can contain various toxic substances. When these tailings are not managed properly, they can leach into groundwater or nearby surface water bodies, causing severe water pollution. This not only impacts wildlife but can also have dire ...
The mining and stripping line is arranged along the ore body trend and moves perpendicular to the ore body trend (Fig. 4).The pioneer cut of the longitudinal cut mining can be excavated along the final boundary of the hanging wall or footwall of the ore body to form a single side working slope, and then advance to the footwall or hanging wall.

به طور کلی، استخراج معدن، فرآیند پس از حفاری معادن در طی معدنکاری است که به برداشت مواد معدنی مورد نیاز بشر منجر می شود. در طی این فرایند مواد معدنی مورد هدف، با کمترین میزان سنگ های زائد از پوسته زمین استخراج می گردند.
An open-pit mining area in Ordos City is chosen to be our research area and we use the GF-1 image to make open-pit mine reclamation areas dataset. Similarly, classic semantic segmentation networks are used for comparison, and verified our improved algorithm on the data of GF-1 and JL-1. In comparing with the sub-optimal algorithms, F1 scores ...
Open-pit mining, or opencast mining, is a surface mining technique used for large-scale operations. It involves extracting minerals from a pit by removing waste rock and overburden. Commonly used for minerals like copper, gold, and iron ore, requires heavy equipment such as trucks and shovels to efficiently extract the ore.
