Abstract:

In order to study the green mining mode of coal, the bottleneck problem in the integrated production logistics system of underground coal mining, dressing, and backfilling under the goal of achieving the basic production capacity target is explored, so as to promote the coordinated and efficient logistics transportation of underground coal and gangue. A mine in Shanxi is selected as the prototype, and the queuing theory is adopted to analyze the operation process of the integrated coal production logistics system. A discrete event model is established with the help of Anylogic simulation software for related experimental optimization and calculation. According to the simulation results, the intelligent sorting system, lifting equipment, and crusher serve as the production bottlenecks of the integrated coal production logistics system, and relevant optimization experiments are carried out to improve the utilization rate of the equipment and promote the coordinated operation of the system.

Key words: integration of underground coal mining, dressing, and backfilling, production logistics system, Anylogic, discrete event simulation, queuing theory
