Intelligent monitoring and control system for blind ventilation with long distance in shield construction of coal mine inclined shaft

An intelligent monitoring and control system was desiged which takes PLC as core for blind ventilation with long distance in shield construction of coal mine inclined shaft. The intelligent monitoring system can automatically adjust ventilator according to change regulation of air flow and pressure of different length of ventilating duct. At the same time, it can monitor environment parameters such as CH4, CO, CO2, O2 and so on in inclined shaft, and send the collected data to mine digital management platform. It ensures safety of ventilation for shield construction.
