Optimalizace větrání dolu Žofie pro bezpečné provozování vodní jámy

Abstract

The presented bachelor thesis deals with the optimization and assessment of the state of the ventilation network at the start of operation of the water well, the current operation of the Žofie water well, and the outlook for further operation of the water well in terms of ventilation and pumping system. The thesis describes the quantity and extent of maintained mine workings depending on the needs of changing the performance of the main mine fan and methods of regulating the fan's performance and ventilation network. Another part of the thesis consists of comparing equivalent cross-sections of the mine, resistance characteristics, and the efficiency of ventilation and the ventilation network before and after the start of operation of the water well. It also evaluates the costs of electricity consumption during the operation of the main mine fan. In conclusion, the thesis provides an overall assessment of the compared parameters and energy costs for operating the ventilation network and fan.
