Abstract：In order to solve the problem of airflow change after the closure of the mining area,a coal mine of Kailuan Group is taken as an example,the length of the ventilation route,the ventilation resistance and the wind resistance of the roadway are measured as the basic data,the single line diagram is drawn according to the ventilation system diagram,and the three-dimensional model of the ventilation system is constructed by Ventsim three-dimensional ventilation simulation system.The function of wind network calculation and airflow simulation of the simulation system is used to simulate the closed scheme of the mining area,and finally the air volume of the roadway meets the design requirements.The results show that after the closure scheme is simula-ted by using Ventsim three-dimensional ventilation simulation system,the total air intake of the mining area is reduced by 14.35m3/s,the total air return is reduced by 12.34m3/s,and the total ventilation resistance of the mine is reduced by 291.7 Pa,which realizes the reduction of resistance and increase of ventilation in the venti-lation system.
