IMPROVEMENT OF THE TECHNOLOGY DEVELOPMENT
OF ROCKS SURFACE MINERS MILLING TYPE
Introduction. For the domestic mining industry, increasing the competitiveness
of production by reducing the cost of production and optimizing all possible links of
technological processes is an important issue.
In connection with the trend of increasing the cost and demand for energy, as well
as reducing the results of rational use of energy resources, there is an urgent need to
improve the efficiency of surface mining of mineral deposits through the use of non-
blasting rock mining technologies. A promising way to solve this problem is the
introduction of the technology of layer-by-layer milling of rocks by surface miners into
the working conditions of iron ore pits, which contributes to the development of half-
rocky rocks and rocky rocks without drilling and blasting.
Based on the analysis of the practice of mining enterprises, the achievement of a
sufficiently high organizational and technical level of production is possible with the
development of advanced technologies with the use of highly productive mining
equipment, which improves the technical and economic indicators of enterprise
production.
Solving the problem of increasing the effective use of excavation and loading
equipment and reducing the cost of raw materials requires the development of
technological schemes. Which take into account to study in detail the cost patterns of
the two technological processes: the preparation of rocks for excavation and excavation
and loading work. Thus, to identify the factors influencing operations included in the
technological process of mining production, which will determine the level and
dynamics of costs for the development of iron ore deposits on the above induced
technological processes, as well as to identify the nature of the optimal values of these
factors of influence.
The most expensive mining process is the preparation of rocks for excavation.
Part of the cost of preparing the rocks for excavation reaches 50% of the total cost of
mining processes.
The traditional technology of opencast mining is the development of semi-rock
and rock rocks with the implementation of a complex of drilling and blasting operations
to prepare the rock mass to be excavated by an explosion. After that, the rocks are
