Subject syllabus:

The methods and ventilation systems of mines, leadership, division and distribution of winds in the ventilation area, SVO, working on ventilation systems and coalfaces diagrams, the main ventilation: equipment for the main ventilation, ventilation station, equipment for introduction and control of underground winds, active and passive control, ventilation losses, wind suction, coefficient of utilization. The economic performance of ventilation, energy performance of the main ventilation, separate ventilation economy, the importance and role of ventilation in the current mining, explanation of basic concepts, systems and forms ventilation of mines, mine pollutants in the air and their detection, mine winds composition according to the requirements of hygiene standards and safety regulations. Laminar and turbulent air mass flow, diffusion and its monitoring, determination of aerodynamic resistance, natural buoyancy and mechanical ventilation. Wind down as a complex balance sheet data on wind, gas and micro-climatic conditions, ventilation of the balance sheet, map documentation, ventilation parameters Q, P, R, A, etc. - their identification and evaluation, separate ventilation, micro-climate, gas ratios, critiques network proposals to improve the overall state of ventilation. Home ventilation of mines: ventilation systems of ventilation areas, ventilation systems and schemes SVO, ventilation systems and coalfaces diagrams (U, Y1, Y2, H, Z, W, ZZ) - advantages and disadvantages, ventilation of other mine, application systems and ventilation schemes SVO and coalfaces while the effects of adverse effects (dust, temperature, methane, mash, shocks, etc.). The main mine ventilators, ventilator arrangement of stations, the characteristics of ventilators, ventilation ducts, intake of loss, control ventilators, ventilators of cooperation, cooperation of the main and auxiliary ventilator, practical applications, examples and solutions to specific situations. Separate ventilation: how to design and project sep. ventilation, leaking calculation air box moves, separate ventilation ventilators, ventilators air box characteristics, air boxes, species air boxes, air box strokes, tightness air boxes moves, practical applications, examples of solutions sep. ventilation intake, mouth, combined, modified sep. combined ventilation. Optimization of the main ventilation, separate optimization of ventilation, energy intensity of the main and separate ventilation, reducing energy consumption, practical applications. Automation in ventilation: scanning the needed parameters, information transfer, processing of measured values, use the data to control ventilation, practical applications. Basic components of air quarries, water vapor, pollutants, highest admissible concentration, the dust in the air quarries, physiological effects, measurement, radiation, sources of pollutants in the mines, the basic laws of atmospheric changes in quarries, thermodynamic processes in the atmosphere quarries. Meteorological conditions and refractive aerodynamics, measurement methodology the meteorological variables wind speed and direction, air temperature, humidity, barometric pressure. Natural ventilation of quarries - convective, inverse, direct flow, recirculation and combined air exchange schemes in quarries. Artificial ventilation of quarries - air free currents isometric and non-isometric, air box, air raises. Innovation of the substance, news of conferences and seminars, and scientific - research activities of faculty.
