The most linearly extensive mining landscapes are generated by open-cast placer mining of gold, platinum, and other precious metals from coarse-grained alluvium in river valleys. Here, the mining of streambed (alluvial) deposits for minerals produces various morphological modifications that intensify sediment generation and delivery processes.

Open-cast Mining. Open-cast mining is one of the most popular surface mining methods mostly employed for bedded deposits. The kind of minerals or rocks mined this way are found near the surface; where the overburden (surface material covering the valuable deposit) is relatively thin or the material of interest is structurally unsuitable for tunneling.

Introduction Open cast mining in South Africa has grown and developed rapidly since its introduction in the mid-1970s when first Optimun and then Arnot collieries commenced open cast operations. Today there are eight large open cast mines employing in the region of twenty draglines. Open cast mining was motivated
The operating cost of mechanized opencast mines has escalated with an increase in prices of essential inputs, like materials, spares, haul-road maintenance, spiraling wages, and improved welfare ...
The life cycle phase of fossil fuel extraction is mainly considered in the life cycle assessment (LCA) when evaluating the energy production processes. It is then only one of many unit processes, which contribute to the blurring of mining-relevant results. There are few items in the literature focusing exclusively on the lignite mining phase and analysing the specific mining …
Opencast mining, also known as open-pit mining or surface mining, is a method of extracting valuable minerals or geological materials from the Earth's surface. Unlike …
1. Introduction. Dust generation and its dispersion has been the major concern in ambient air quality in deep cavities such as open cast mines. Major mining activities in deep open pit coal mines range from exploration to the processing of end product that primarily contribute particulate matter (PM), dominantly PM 10 leading to the problem of air pollution and related …
The situation has been reviewed by experts and scientists and, in the present decade, there has been a pronounced-up gradation in the mining industry, especially in open cast mining. More technologically advanced, automated and capital-intensive heavy earth-moving machinery (HEMM) are now available and deployed to meet the high demand for ...
8.4.1: Dredging or Dredge Mining. A dredge is the principal piece of equipment used in the dredging method and, essentially, a dredge is a boat containing specialized mining and materials handling components. Accordingly, a dredge requires a body of water in which to operate. In many cases, this is a natural body of water such as a river or a lake, but in others, it is a man …
This paper details the optimization framework model for managing the schedule of the movable mining equipment of open cast mines to improve the availability and productivity of the mining equipment.
Open cast mining is a method used for extracting minerals and resources from the earth's surface. This technique involves removing large areas of overlying soil and rock to …
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 …
of the open pit is 450 m, and its dimensions are 4 by 5 km. Annually, about 50 million cubic metres of mined rock is car-ried from the open cast of the plant. There is a linguiform island of rock at the centre of the open cast. It is a dead rock, and this area has been avoided lest the time be expended for its removal
The production cycle of open-cast coal mines generally includes drilling, blasting, loading, hauling and coal preparation activities. Individual optimization of these activities does not mean that the whole system is optimized. This paper proposes a cost model considering all activities in mining cycle and system-wide approach to minimize the total mining cost of bench …
Open-cast mining is a surface mining method where the overburden in is not transported to waste dumps for disposal, but cast into adjacent mined out panels.
