of South African open cast coal mine highwalls
Open cast mining has been practiced in South Africa since the late 1970s under near ideal geotechnical conditions. In the past decade, with the exhaustion of the traditional South African coal fields, geotechnical conditions have deteriorated. In addition, the nature of the open cast coal mining industry is changing from the conven-Open pit mining method is one of the surface mining methods that has a traditional cone-shaped excavation and is usually employed to exploit a near-surface, nonselective and low-grade zones Open Pit Mining IntechOpen

Mining and Stripping of Open Pit SpringerLink
Download reference work entry PDF. Mining and stripping of open pit is the method of stripping rocks and mining ores from open-pit mine according to a certain mining order. In open-pit mining, there is little difference between the process of stripping rock and mining ore. The equipment on a working bench can be used for both mining Open pit mining is based on dynamic operations within the open pit, with the haulage operation being the most decisive in terms of the cost and the overall productivity of the operation. A vital aspect for the success of the haulage operation are the conditions of the roads, which change over time due to wear and tear.

slope: The Manglai open-pit coal mine Landslide mechanism and
Open-pit mining is a frequently used method to develop mineral resources, and the landslide disasters of high and steep slopes caused by mining are directly related to the vitality of mines (Carlà et al., 2018; Li et al., 2019; Vinoth and Ajay Kumar, 2014). For example, the landslide accident at the Shengli East No. 2 open-pit where: H 1 —the height of the lower interbed, m; H 2 —the height of the upper interbed (between the second and the third seams), m. The lower part of quarry field with a height of 35–55 m comprises two flat seams and is being processed by dragline mining method. As for the volume of coal production it is the leading one, as it provides Justification of Open Pit Mining Technology for Flat Coal Strata

Phase Planning for Open Pit Coal Mines through Nested Pit Generation
This paper presents a phase planning method specially designed for coal deposits with nearly horizontal, bedded coal seams. The geology of this type of deposit is modeled into a column model, instead of a block model, to avoid coal-rock mixing in blocks. A nested pit generation algorithm is developed for producing a series of nested, least In the following, an overview of recent research papers relevant to management of open-pit ST system is presented in chronological order.

Intensive mining activities in large-scale opencast coal mines have had a significant impact on the local environment. Elements that are potentially harmful to the environment are brought to the surface from deep underground, altering the geochemical conditions for their transport and redistributing them to the surface, causing serious local In this study, a solar-powered multipoint network monitoring method was used to record dust-particle concentrations and meteorological indicators in the Anjialing open-pit coal mine in the Analysis of the Dust-Concentration Distribution Law in

Frontiers Dynamic optimization of open-pit coal mine
A dynamic optimization method was created to address the production schedule issue in an open-pit coal mine while taking into account the characteristics of the fuzzy structured element. The fuzzy mining capacities of all “geologically optimal push-back bodies” were then examined using the moving cove method. One of the most crucial As the province most abundant in mineral resources in China, Inner Mongolia has more than 200 open-pit coal mines. The coal mining activities seriously hinder the sustainable use of regional land and the improvement of residents’ wellbeing. Taking 13 typical open-pit coal mines of Inner Mongolia as the study area, combining The Landscape Pattern Evolution of Typical Open-Pit Coal Mines

Research on Ecological Effect Assessment Method of Ecological
Open-pit mining is an important form of coal mining in China, and its damage to the ecological environment is particularly obvious in alpine regions. The ecological restoration of alpine open-pit coal mines faces severe challenges, and its restoration effect will directly affect the ecological security of China. Meanwhile, At present, the open-pit coal production of China ranks second in the world (Wang Citation 2014) and is developing toward a large-scale direction.It has been proven that large-scale open-pit coal fields are concentrated in Xinjiang, Inner Mongolia, and other ecologically vulnerable areas (Jiskani et al.
