【Abstract】 As mining depths in Xinzhuang coal mine increases, the air quantity in some working places is short. Therefore, a mensuration of the resistance of ventilation system has been performed. A computer program is used to analyse the ventilation system during different periods based on the data obtained in the mensuration,. According to the result of calculation, an optimizing technical transformation plan for ventilation system is put forward to solve the problem.更多还原
