摘要（英）：

The invention discloses a coal mine underground fully mechanized coal face coal flow monitoring and control system and relates to the technical field of electromechanical integration. The fully mechanized coal face coal flow monitoring and control system mainly comprises a centralized control device, a coal flow monitoring device, a frequency changer, a coal cutter and a scraper blade conveying machine. The concentrated control device and the frequency changer are located on a crossheading equipment rail; the coal cutter and the scraper blade conveying machine are located on a fully mechanized coal face, and the coal flow monitoring device is installed on the scraper blade conveying machine and used for monitoring the amount of coal on the scraper blade conveying machine in real time. The frequency changer controls starting, stopping, accelerating, decelerating and other actions of the scraper blade conveying machine; the concentrated control device is used for collecting data of the coal flow monitoring device in real time and outputting control signals to the frequency changer and the coal cutter according to the coal amount. The system is used for the coal mine underground fully mechanized coal face; the coal flow of the fully mechanized coal face can be monitored and controlled; the occurrence rate of coal pile accidents is reduced; the purposes of energy conservation and consumption reduction are achieved.
