英文摘要：

In order to solve the difficulties of ventilation, unreasonable distribution of ventilation resistance and low efficiency of fan in Zhilanchong Coal Mine, this paper proposes three optimization programs to the current situation of the coal mine＇s ventilation based on ventilation parameters measured results. Three- dimensional ventilation simulation system of Zhilanchong Coal Mine is built by Ventsim software. Through simulation and analysis, the plan has been determined and ventilation system of Zhilanehong Coal Mine has been successfully optimized. The stability of ventilation system and the efficiency of fan running are improved. Results show that ventilation system simulation is authentic. It is of guiding significance for the coal mine ventilation management and the transformation of ventilation system.
