Goal

The purpose of the discipline is to develop in students the knowledge, skills, and practical competencies required for the maintenance, diagnostics, repair, and restoration of mining equipment used in underground mining operations, as well as to ensure an understanding of the principles of reliable, safe, and efficient operation of machinery in complex mining and geological conditions.

Objective

Study the types and designs of mining equipment used in underground mining operations, as well as the specific features of its operation in complex conditions. Develop knowledge of the types of maintenance, the frequency and scope of service, and the technology for performing scheduled and unscheduled repairs. Master methods for diagnosing the technical condition of equipment, including vibration diagnostics, thermal imaging control, and wear and defect analysis. Train students to identify the causes of malfunctions, conduct technical failure analysis, and select optimal methods for eliminating defects. Acquire technologies for component restoration, including welding and surfacing, mechanical processing, thermal spraying, and other repair methods. Develop skills in planning and organizing repair work, preparing maintenance schedules, and creating operational documentation. Form an understanding of industrial safety requirements, occupational protection, and the reliable operation of equipment in underground conditions. Support the development of professional competencies, engineering thinking, and the ability to apply knowledge in practical repair activities.

Learning outcome: knowledge and understanding

A student must know and understand the design, purpose, and operating principles of mining equipment used in underground mining operations; the types of maintenance and repair; the methods for diagnosing technical conditions; the causes of equipment malfunctions; and the requirements of industrial safety and reliable equipment operation in underground conditions.

Learning outcome: applying knowledge and understanding

The student is able to apply theoretical knowledge to perform maintenance, diagnostics, and repair of mining equipment used in underground operations. They can select optimal methods for restoring components, utilize modern diagnostic techniques (vibration diagnostics, thermal imaging, wear analysis), and develop and carry out technological repair procedures. The student can identify the causes of equipment failures, make well-grounded engineering decisions, and comply with industrial safety requirements while performing repair work in underground conditions.

Learning outcome: formation of judgments

The student is able to critically evaluate the technical condition of mining equipment used in underground operations, apply engineering analysis to justify the need for repair or replacement of components, and formulate well-reasoned conclusions when selecting optimal restoration technologies and diagnostic methods. The student can assess the risks of equipment failures, compare different repair strategies in terms of reliability, safety, and economic feasibility, and take underground mining conditions into account when choosing technical solutions. They are capable of developing and defending engineering proposals aimed at improving the efficiency and durability of mining equipment.

Learning outcome: communicative abilities

The student is able to clearly and professionally communicate information related to maintenance, diagnostics, and repair of mining equipment used in underground operations, both orally and in writing. They can effectively collaborate with engineers, mechanics, and technical personnel in solving operational tasks in underground conditions. The student is capable of preparing technical reports and diagnostic documentation, presenting and defending proposed engineering solutions, and actively participating in team-based work and production meetings.

Learning outcome: learning skills or learning abilities

The student is able to independently study technical literature, regulatory documents, and operational manuals related to the repair of mining equipment used in underground operations. They can analyze modern scientific and engineering solutions aimed at improving the reliability and durability of machinery and apply the acquired knowledge for further professional development. The student demonstrates the ability for self-directed learning, mastering new repair and diagnostic technologies, critically evaluating their own competencies, and identifying areas for improvement. They are capable of adapting to new technical challenges and the specific conditions of underground equipment operation.

Teaching methods

Lecture–seminar–assessment system; collaborative learning (teamwork and group work); information and communication technologies; project-based learning; research-based learning method.

Assessment of the student's knowledge

Teacher oversees various tasks related to ongoing assessment and determines students' current performance twice during each academic period. Ratings 1 and 2 are formulated based on the outcomes of this ongoing assessment. The student's learning achievements are assessed using a 100-point scale, and the final grades P1 and P2 are calculated as the average of their ongoing performance evaluations. The teacher evaluates the student's work throughout the academic period in alignment with the assignment submission schedule for the discipline. The assessment system may incorporate a mix of written and oral, group and individual formats.

Period	Type of task	Total
1 rating	An individual assignment is issued to each student for the rating assessment.	0-100
2 rating	An individual assignment is issued to each student for the rating assessment.	0-100
Total control	Exam	0-100

The evaluating policy of learning outcomes by work type

Evaluation form

The student's final grade in the course is calculated on a 100 point grading scale, it includes:

40% of the examination result;
60% of current control result.

The final grade is calculated by the formula:

FG = 0,6	MT₁+MT₂	+0,4E
	2

Where Midterm 1, Midterm 2are digital equivalents of the grades of Midterm 1 and 2;

E is a digital equivalent of the exam grade.

Final alphabetical grade and its equivalent in points:

The letter grading system for students' academic achievements, corresponding to the numerical equivalent on a four-point scale:
