摘要
本文介绍了在实验室做煤尘模拟实验时选择粉尘的方法步骤。实验用的粉尘应选真实煤尘，其Ｆ曲线与现场煤尘的Ｆ曲线相同时，实验结果才准确可靠。
This paper introduces the method and procedure of selecting dust when the coal dustsimulation experiment is done in the laboratory. Real coal dust should be selected for the exper-iment,when F--curve of which is the same as that of coal dust on the spot,the experimental re-sult is accurate and reliable.
