Çayırhan kömür madeni g sahası için havalandırma modeli geliştirilmesi

Ventilation problems raised with the beginning of underground mining. In underground mining, to provide safe and healthy working conditions, ventilation should be designed properly. Especially in the planning stage of the project, to design ventilation properly is very important. The latest upgrade of the popular ventilation simulation program, known as VnetPC 2000, has been applied for the ventilation design. In this study simulation is conducted to both auxiliary and main ventilation at Çayirhan G Field. Information describing the geometry of a ventilation network, airway characteristics and locations, characteristics of different fans were prepared as an input. The output includes predicted airflows, frictional pressure drops, air power, losses in airway and fan operating points for different trials. After different trials it has been found that for auxiliary ventilation, where minimum required amount of air is 6 m3/s, ENGART, 30A 40SCV/60HR model fan which is the most economical one was selected. For main ventilation system, 5 fans which provide airflow more than minimum requirement were chosen. Among them the most economical one, that is ALPHAIR-5400VAX2100 HB, was selected for the mine.M.S. - Master of Scienc
