Aiming at the great challenges of the stockyard layout and coal grade distribution management of the coal export terminal，caused by the variety of coal types and stack positions，the complex stockyard operation and coal blending process，We take the first phase project of Huanghua Port as an example，carry out optimization research on the throughput capacity of coal stockyard. Under the condition of the original process plan，we analyze actual operation data，optimization process selection，the stock position size and the coal type adjustment，and use the computer simulation method to calculate each scheme and obtain the optimal scheme of the stockyard throughput capacity. The results show that when the traditional loading and unloading process scheme design and technology implementation difficulties，using simulation method for integrating operation management and strategy to the scheme design can provide theoretical reference and data support for coal export terminal stockyard layout，and also lay the foundation for wisdom of the coal terminal upgrade.
