Abstract：Aiming at the high concentration dust in the process of fully mechanized coal mining face in underground coal mine, the hydraulic support automatic dust reduction system is developed to improve the underground worLing environment. The system taLes PLC as the core control unit, signal acquisition can be carried out by the dust sensor and the infrared sensor is arranged on the hydraulic support. According to the collected signal, the system sends the appropriate instructions to the solenoid valve, then the switching states of the negative-pressure secondary dedusting device is controlled by the automatic dust reduction system, and the automatic control of dust concentration in fully mechanized coal face is realized. The designed intelligent dust reduction system was tested in 5302 fully mechanized coal mining face of Zhaolou Coal Mine, the test result showed that, after application of the automatic dust reduction system, the dust concentration in whole worLing area of fully mechanized coal face was reduced, and the worLing environment was significantly improved.
