Technology of Underground Ore and Non-Metal Mineral Deposits Development

Description: The number of deposits easily developed at relatively shallow depths is decreasing, and the properties of ores and other minerals are significantly changing qualitatively. Thus, the share of ores, mainly sulfide ores, prone to spontaneous combustion, rich multi-grade polymetallic ores that are difficult to process, has significantly increased. Therefore, mining specialists use previously accumulated experience, the results of scientific research, and become a researcher.Compliance with the requirements of the legislation of the Republic of Kazakhstan in the field of industrial safety at facilities conducting mining and geological exploration.

Goal

• The purpose of this course is for students to study technical solutions for the opening, preparation of deposits, the study of systems for the development of ore and non-metallic deposits, consideration of the procedure for opening, preparatory and rifling workings, mechanization and organization of technological processes

Objective

• As a result of studying the section "Opening and preparation of deposits", the student must: - acquire knowledge about the design of a mining network at the stage of field operation; - study the methods of the developed mining network in the conditions of a specific enterprise; - be able to choose rational ways of preparing mine fields; panels, blocks, floors, tiers, taking into account modern mining equipment and increasing the depth of mining operations; - acquire skills in spatial orientation of the location of workings relative to mineral deposits, making informed technical decisions. When mastering the "Development Systems" section, the student should study: - the order and sequence of preparatory and rifling work; - design of the development system and methods of rock pressure control; - classification of development systems; - methods for determining the parameters of development systems; - identify ways to improve them.

Learning outcome: learning skills or learning abilities

• To improve existing and introduce advanced research methods, mobility and susceptibility to the improvement of equipment and technology, the use of achievements of scientific and technological progress in the field of mining

Teaching methods

The educational work is carried out using both traditional technologies and modern interactive ones. Lectures are held in the traditional form. Practical classes allow the teacher to communicate more individually with students and are suitable for interactive teaching methods.
