Natural wind pressure is the main influencing factor affecting the stability of mine ventilation system.Aiming at the increasing depth of mining in Tangkou Coal Mine and the increasingly complex characteristic of the mine ventilation system,exploring the changes in natural wind pressure in the southern wing well area of Tangkou Coal Mine is of great significance for the stability of the mine ventilation system in the southern wing well area of Tangkou Coal Mine.In order to study the natural wind pressure situation in the southern wing well area of Tangkou Coal Mine,on-site measurement and theoretical analysis are used to measure its natural wind pressure and analyze its variation laws.The results show that the natural wind pressure of Tangkou Coal Mine shows a law of lowest at noon and highest in the morning and evening in each season,and the natural wind pressure in spring,summer,and winter is positive,while the natural wind pressure in summer is negative.Both temperature and relative humidity have a certain impact on natural wind pressure,but the variation law of temperature and natural wind pressure is opposite,while the variation law of relative humidity and natural wind pressure is basically consistent.
