Application of (CAD) Modeling in Selection of Open Cast Mining Machines for Complex Structure Ore Deposits in Training of Mining Engineers

Abstract

Urgency of researching issue determined by creating a prognosis for analyzing specific
mining and geological conditions and physical and mathematical properties of rocks
in selecting types of mining machines like scrapers, bulldozers and combines. The aim
of research: To search dependency between types of mining machines and properties
of mining face and physical and mathematical characteristics of mined rock, to exclude
possibility of risks and mistakes in projecting of surface mining objects using CAD
systems. Methods of research: Mathematical and statistical modeling, analyzing of
technical and project documentation of load and haul machines, prognosis of using
special open-pit equipment with regard to researching of its quality, usability and high
mobility, method of successive approximation, generalization, concretization, synthesis
in studying of equipment performance, computer modeling. Results of research: Rising
professional competency of students, as important factor of ecology, culture and
education. Has been established determination of annual production rate of main
open-pit equipment has been established. Have been developed engineer
technologies and rational organization of running mining and loading works and load
coefficient of open pit equipment. Have been conducted research and analyze of
dependencies for production rate determination of scrapers, bulldozers and combines
performance and developed fields of their application. Has been accomplished
modeling of technological processes of bulldozer mined rocks. Practical meaning: This
article aimed on adaptation of educational process to new conditions, in which it exists
and orientated on development of perspective methodical and educational support of
mining disciplines. Information represented by this article can be useful for
professionals working in industry and projecting organizations which connected with
open cast mining of complex structure ore deposits.
