Component: Component by selection

Cycle: Profiling disciplines

Goal

• The purpose of the discipline is to provide the theoretical foundations of knowledge about the main methods of opening and preparing deposits, to develop skills for making technical decisions when opening deposits underground.

Objective

• Objectives of the discipline: - study of the main criteria for evaluating the justification and selection of rational methods and schemes for opening reserves of mineral deposits; - determination of the values of the opening step and the length of mine fields, taking into account the timing of reserves development; - obtaining skills in substantiation and selection of types and types of mining vehicles and equipment for opening workings to ensure the production capacity of mining enterprises; - study of methods for making optimal decisions when designing schemes for opening mining enterprises with an underground mining method.

Learning outcome: knowledge and understanding

• Knowledge and understanding of the main methods and schemes for opening reserves of ore and non-metallic deposits.

Learning outcome: applying knowledge and understanding

• Application of knowledge and understanding: design of opening schemes and justification of the parameters of the main opening workings when justifying the opening of ore and non-metallic deposits.

Learning outcome: formation of judgments

• Formation of judgments: To justify the adoption of strategic technological decisions on the formation of opening schemes and the choice of the sequence of reserves development in the mine field during the development of ore and non-metallic deposits by underground method.

Learning outcome: communicative abilities

• Communication skills: determination and analysis of technical and economic indicators of autopsy and preparation schemes.

Learning outcome: learning skills or learning abilities

• Learning skills or the ability to study: to design or accept standard sections of opening and preparatory workings.

Teaching methods

collaboration (teamwork, group work); information and communication technologies; technology of project training; research method of teaching.

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.

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:

 

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:
