[0002] Gangue generally refers to coal gangue, which is a kind of solid waste generated during the underground mining process of coal mines. The coal gangue generated underground is generally temporarily stored in the corresponding gangue bin according to the principle of proximity, so there are usually multiple gangue bins in the underground, and then unloaded onto the corresponding gangue conveyor belt and then transported to the gangue field on the well. However, the existing gangue storage, unloading and transportation systems mainly have technical problems such as monotonous equipment operation, inflexibility, large manual maintenance workload, uncentralized start and stop control, and low degree of intelligent control, which leads to inadequate monitoring of various system equipment, failure problems cannot be handled in time, equipment performance is difficult to play to the best state, and labor costs are high, affecting the overall economic benefits of coal mines.

[0003] In recent years, in response to the call of "building smart mines", most coal mining companies have also been actively developing intelligent mine monitoring systems. For example, the patent document with publication number CN115199323A provides an intelligent storage-type mechanical horizontal gangue bin, which can greatly improve the dependence of traditional coal mine gangue storage systems on manual operation. The automation level of operation and control of each component equipment in the system (such as belt conveyors for transporting gangue, mobile distributors for belt unloading, mechanical gangue bins for storing gangue, hydraulic valve plates for controlling gangue bin unloading, and discharge conveyors for discharging and transporting under the gangue bin, etc.) has been improved, which has greatly improved the efficiency of mine gangue storage and transportation.
