Abstract: The most difficult, labor-intensive and costly part of the process of developing mineral deposits in an open-cut way is the transportation of rock mass, which is 60-75% of the production cost. The main type of technological transport used for the transportation of rock mass is mining dump trucks with diesel engines. At the same time, the world mining industry consumes billions of liters of diesel fuel annually. A significant disadvantage of diesel vehicles is the gas content of the atmosphere, especially in deep horizons. The exhaust gases from diesel vehicles have a harmful effect on human health and the environment.
To ensure sustainable operation, mining enterprises pay more and more attention to the energy factor. Companies are seeking to reduce operating costs by reducing the transporting rock mass cost, which has resulted in renewed interest in trolley transport.
The use of power from an air contact network allows to reduce the weight of the dump truck by 10-15% by eliminating the diesel engine, fuel and oil tanks, oil and water radiators, exhaust systems and a number of others while maintaining the same load capacity.
Various designs devices are used to power vehicles from an overhead contact network. The current collectors of open-pit trolleys have specific requirements due to the operating conditions.
The current collector of a mining dump truck should also have broad capabilities for automating the processes of installing current collectors on the line and leaving it. This is necessary to reduce the time spent on the installation and removal of current collectors from the line, and to save the dump truck driver from manual labor in these processes.
