The invention provides a layering automatic stockpiling method of a stockpiling machine. The method comprises the following steps that (1) known stockpiling yard information is written into a PLC control system, a three-dimensional stockpiling yard model is established, and the stockpiling yard information is adjusted specific to different stockpiling conditions; (2) a layering procedure is established in the three-dimensional stockpiling yard model; and (3) the layering procedure is added into an automatic stockpiling procedure of the stockpiling machine, and the stockpiling process is changed into a layering stockpiling process. According to the method, operation is convenient, a stockpiling driver is not needed, and the labor cost for the stockpiling driver is reduced; the existing automatic stockpiling function is broadened through layering stockpiling, and stockpiling can be conducted according to the standard settings and can also be conducted in an adjusted mode, so that stockpiling stack models are diversified; an operator only needs to remotely operate in a central control room, and the influences of outside weather such as rain, snow and strong wind are avoided; and the piling efficiency and piling precision are quite high.
