Content:
Theory teaching Introduction (1 week): - Introduction to the course, concept of teaching and the exam. - Application conditions, advantages and disadvantages depending on the mode of operation. Basic terminology, technology and production processes in mining. - Requirements to be fulfilled by machines in working conditions on surface mines and mines with underground exploitation. - Classification of machinery and equipment and mining, historical development of mining machines. Basic components of machines and devices in mining (4 weeks): Propulsion systems (internal combustion motors, electric motors, hydraulic and pneumatic motors); Power transmissions (mechanical power transmission, hydrodynamic power transmission, hydrostatic power transmission, electric power transmission). Transport equipment on mining machines: devices with wheels (wheels, supporting structure, suspension), tracked devices (crawler drive, structure, suspension), rail devices, walking devices, combined units. Stability of the transport system. Specific pressure on the ground. Control devices. Braking systems. Excavation units on mining machines. Machines and devices for underground exploitation (4 weeks): - Machines for excavation and drilling (classification, construction, application, safety measures). - Loading machines (division, construction, application, safety measures). - Machines for continuous and discounted transport (classification, construction, application, safety measures). - Devices for the upgrading of excavated space (classification, construction, application, safety measures). Surface mining machines and devices (5 weeks): - Surface drilling machines. – Surface excavating and loading machines. - Machines and devices for the transport on open cast mines. – Auxiliary machines on open cast mines. – Stackers and spreaders. Mineral processing machines (1 week): - Crushing plants Practical teaching At exercises, students take three colloquiums through tests. Colloquiums topics are logical units (machines and devices for underground exploitation, machines and devices for surface exploitation and machines and devices for PMS and auxiliary and preparatory works). Remaining classes are related to practical examples of the selection of machines, verification of the capacities, as well as the calculation and sizing of machines and individual assembly sets. |
