Discrete Element Method-Based Simulation Analysis of the Horizontal Mechanical Coal Bunker System

The underground horizontal mechanical coal bunker system is an important component of the coal mine transportation system. Due to the solid-liquid characteristics of coal particles, the flow characteristics of coal particles during the loading process of the coal bunker system are very complex. Under certain conditions, problems such as leakage of the upper discharge baffle of the coal bunker, blockage of the discharge port of the unloading cart, low loading rate of the coal bunker, and even partial loading and overturning of the coal bunker may occur. This paper takes the underground 1000 ton level mechanical coal bunker developed by the company as the analysis object, uses discrete element analysis software to simulate and analyze the coal bunker system, obtains the flow characteristics of coal particles in the loading process of the coal bunker system, optimizes the structure of the coal bunker system and the loading process, and provides theoretical support for the design and successful application of the coal bunker system.
