Purpose of the work is to increase the energy saving of a mining enterprise by using electricity and reducing the cost of diesel fuel.
Methodology of the work. Analysis of possible ways for energy saving of a mining enterprise.
Results of the work. The extraction industry is one of the main consumers of energy, therefore, mining companies put a greater emphasis on energy saving measures and cost-effective ways of energy generation. One of the largest expenditure item when mining is the energy required for extraction and processing of mineral ores. While the development of mineral deposits, the main type of technological transport is a motor vehicle with diesel engines. The global extraction industry spends billions of liters of diesel fuel annually to transport rock mass. Along with many advantages, diesel engines have some disadvantages as well. One of the promising areas of energy saving of a mining enterprise is the use of electricity. This leads to savings in diesel fuel and reduced exhaust emissions. Five main ways of power supply to an engine are considered: additional power cable, air contact network, built-in battery, fuel cells, electric generator, and trucks with a combined power plant.
Conclusions. Improving the efficiency of the mining enterprise can be achieved through significant fuel savings, higher productivity of the transportation process of rock mass, reduction of vehicle fleet, reduction of operating and maintenance costs. An electric motor drive allows you to increase time between engine repairs, reduce the cost of energy consumed by regeneration and return it to the network, as well as reduce or eliminate emissions of exhaust gases.
