Abstract: Gangue is the associated waste of coal mining. Separation of coal and gangue is a necessary process in the process of coal mine production. Improper separation of gangue will directly affect the coal washing process and coal quality, and seriously cause damage to coal washing equipment. In this paper, aiming at the problems of high labor intensity, high safety hazards and low gangue picking rate in the traditional manual gangue picking in the north well coal preparation plant of Dongpang Mine, the system of raw coal gangue discharge is optimized according to the current situation of the plant, and the automatic intelligent gangue selection device is used to replace the manual gangue selection, so as to improve the detection rate of gangue and the safety of operation. In this paper, the current various types of raw coal gangue separation processes are compared and analyzed. The working principle and technical process of the PIDS belt intelligent dry separation system are described in detail, and the technical advantages of the raw coal intelligent dry separation system are summarized. The practical application scheme of the system and the economic and social benefits obtained are described, indicating that the PIDS intelligent dry separation system has a good promotion value in the process of raw coal gangue discharge in similar coal preparation plants.
