N2 - During the development of the Malyshev titanium-zirconium ore deposit in Ukraine, the richest parts were worked out. Under the conditions of increasing demand on titanium in the world and the development of technologies, it was decided to mine a new section to ensure the necessary supply of the existing processing plant by ore. The purpose of this thesis is to justify the most effective technological scheme for the Motronivka-Annivka section development. The most effective is a technological scheme in which investments and natural resources are used as efficiently as possible. Therefore, the method used in this thesis is a comparison of possible technological schemes of the field development by their capital and operational expenditures. In the thesis, schemes using the following mining equipment are considered: bucket-wheel excavator, dragline excavators and hydraulic excavators. When developing technological schemes, the organization of the interconnected operation of the equipment within the whole open-pit area was analyzed. Also, in this work, technical and economic dependencies were studied and analyzed when changing work parameters. These studies have helped to justify the choice of equipment and the working schedule of the mine. Furthermore, these calculations have allowed to study the modes of mutual work of equipment to achieve to ensure its maximum performance. Engineering drawings of whole mine work organization for all considered technological schemes are presented in Attachments for this thesis.
