Aiming at the simple control mode of the existing mine ventilation system,which is unable to identify people and vehicles,and the problem of vehicles touching the dampers often occurs,a new type of laser-sensing automatic dampers is developed,and the design scheme and control logic of the dampers are analysed in detail.According to the actual application in the coal mine,the new control system can realise the automatic identification of people and vehicles,and reduce the collision rate of people and vehicles to 0％,which is of great significance to ensure the safety of people and vehicles.
