An open-pit mine is a large area consisting of mining and processing sites. Material, either ore or waste (overburden), is extracted from mining sites and placed in large trucks. Ore-laden trucks move the material to a site for additional processing or storage, while waste-laden trucks carry the material to a dump site. Each time a truck …

Open-pit mining is a type of surface mining used to extract coal, gold, and other minerals. It creates immense water and air pollution, disfigures landscapes, and destroys habitats.
BHP implemented the autonomous solution at its Jimblebar iron ore operation in Pilbara, completely transitioning the operation to autonomous trucks. To be served by 797F CMD trucks, Newmont's Boddington gold mine in Australia will become the world's first open-pit gold mine with an autonomous haul truck fleet.
Despite the flexibility and acceptability of the truck-shovel system in the transportation fleet of open-pit mining, it requires a big investment. Many attempts have been made to improve shovel and truck equipment based on manufacturing technology to reduce operational costs in mining projects ( Lizotte and Bonates, 1987 ).
Abbaspour et al. [30] developed a simulation model such that safety and social indexes are included in selecting the open-pit transportation system. Samavati et al. [31] proposed a new integer programming model for mine production scheduling using IPCC as transportation means in an open-pit mining operation.
In this research we developed an optimization model to determine truck allocation in open pit mining. The objective function is to minimize a total cost consists of investment and transportation ...
The results of the work on the scientific and technical framework of the open pit mine haulage machinery design for the national standard initiated by ALROSA Group in 2015 are presented. The experience of design and operation of haulage systems at open pit diamond mines in the permafrost zone is analyzed. Favorable operating conditions of …
Open-pit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. Open-pit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels. This surface mining technique is used when mineral or ore deposits …
A method that optimizes mining complexes which are comprised of multiple processing destinations, open pits and underground operations is presented. Mining, blending, processing and transportation decision variables are simultaneously optimized while accounting for...
The Muruntau gold mine employs open-pit mining and heap leach processing. Gold mining is conducted using a truck and conveyor ore transportation system. The overburden is taken to the crushing and …
It is also matched with real open-pit mine product to reduce transport costs, overall unmanned vehicle wait times and fluctuation in ore quality.
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 and stripping.
In-pit crushing and conveying (IPCC) systems have attracted more interest among miners as an alternative to the conventional truck-shovel transportation system. The semi-mobile IPCC (SMIPCC) system is a well-suited type of IPCC system in open-pit mining projects because of its relocation nature.
Specific development themes within this initiative should include SM open-pit intensive mining technology and equipment, high-efficiency open-pit continuous transportation technology and equipment, and SMs in complex environments.
It is a process in which means of transport are adopted to transport ores and waste rocks from open pits to the designated unloading points and waste dumps, respectively, and transport the personnel, equipment, and materials to the working place. It is the key link of open pit mining.
