Abstract:
In modern conditions, when the cost and even the shortage
of fuel and energy resources are increasing, the assessment of the energy
efficiency of industrial technologies is of particular importance. This article
discusses the general principles of scientific substantiation of the energy
efficiency of quarry transports and their evaluation by criteria for reducing
specific energy consumption in the management of drilling, explosion
protection, and excavation processes. the consumption of motor transport is
solved in connection with the consideration of the thermal energy of diesel
fuel in the calculation and the electric energy of conveyor transport and rail
transport in comparison.
Keywords:
Quarry, CFT, Dumping, Enrichment, electric energy, conveyor
transport, railway transport
In recent years, the energy method for evaluating open-pit mining has
received the greatest development in the works of prof. I.A. Tangaeva. In
any technological process, he distinguishes three energy components:
Theoretical energy intensity of the process - the estimated specific
amount of energy required for a given change in the physical state and
spatial position of the object.
Specific energy consumption is the total amount of energy consumed
in a given technological process per unit of output.
The specific energy intensity of the process is the physical specific
amount of energy consumed in a real technological process to change the
physical state and spatial position of a unit of mass or volume of rock. In this
case, the specific energy intensity of the process Ef (MJ/t, MJ/m3) is
recommended to be determined as the difference

where E - specific energy consumption, MJ / t (MJ / m
