Abstract: Based on monitoring and control theory，the mine ventilation control system is developed by building a small volume of the mine model with PVC pipe.This system avoids a large area of underground tunnel excavating needed in ventilation experiments and makes significant cost savings.At first，it places the pressure sensors，wind speed sensors and throttle actuator at suitable locations in the model，then achieves the ventilation parameters of signal acquisition，as well as automatic control of throttle control and other functions through the computer control technology.After model debugging is finished，the mine ventilation resistance testing laboratories，the network solver verification experiment，ventilation network regulation experiments，as well as the diagonal structure analysis experiments have been completed step by step.The experiments of gathering analog signal of pressure and wind speed as well as outputting angle control signal of throttle have achieved good results，which is under the control of software with Visual Basic program language and transmit orders through CAN-BUS bus.The completion of the system is of great importance for the simulation experiment and intelligent diagnosis of mine ventilation.
