Abstract:

The north block of Sangrood coal mine is located in the western Alborz area near to the k h a n city. First extract designing of mine was provided but up to now there is no designing for ventilation system so the main issue in this project is the suff~cientd esigning of ventilation system for providing enough air mine. In order to design the ventilation system of the mine, in the first step, air flow in the productions face was calculated for dilution of methane gas and final airflow required 1998 m3/mine.1n the second step,final pressure losses was calculated that it caused to increased air flow to 2114 m3/min. The third step, fan was studied that it can provide 2114 m3/min air flow and 165 mmwa pressure losses.FinaIly,computer simulation has been used for ventilation system.
