Throughput capacity of inland coal terminals with multiple berths and few threads and influencing factors

针对新工艺下的煤炭码头合理通过能力评估问题,结合内河煤炭码头规划建设工程,深入分析多泊位少线程煤炭码头的生产作业过程及生产能力影响因素,应用系统仿真技术建立该装卸工艺的煤炭码头物流系统模型,对顺岸式布置的煤炭码头通过能力与装船效率、船舶辅助作业时间、船舶移泊时间之间的关系进行试验研究。结果表明,多泊位少线程装船作业模式能够满足码头1 400万t吞吐量需求,船舶到达密度与年吞吐量的关系最为密切,而到港辅助作业时间和移泊时间对港口服务水平和装船机利用率有较大影响。

Regarding the evaluation of the reasonable throughput capacity of coal terminals adopting the new technology, this paper analyzes in depth the production operation process of coal terminals with multiple berths and few threads and the factors influencing their production capacity by investigating the planning and construction of an inland coal terminal project. Then, it employs the system simulation technology to build a logistics system model for the coal terminal adopting the loading and unloading technology and experimentally examines the relationships of the throughput capacity of the coal terminal arranged along the shore with the loading efficiency, the auxiliary operation time of the ships, and the berth shifting time of the ships. The results show that the multiple berths and few threads loading operation mode can meet the 14-million-t throughput demand of the terminal. Moreover, the ship arrival density is most closely related to the annual throughput, and the post-arrival auxiliary operation time and the berth shifting time have a large impact on the service level of the port and the utilization rate of the ship loaders.
