[0012] 1) Arrange single type of coal to each corresponding coal bunker, so that the two lines of coal types are kept corresponding, that is, the first row of coal bunker 1 and the second row of coal bunker 2 are kept one-to-one corresponding. For example, the first row of coal bunker 1 has gas coal, coking coal, fat coal, and lean coal, and the second row of coal bunker 2 must also arrange gas coal, coking coal, fat coal, and lean coal symmetrically. And the quality indicators of the corresponding coal types are balanced.

[0013] 2) Arrange the largest proportion of coal types to be in both rows.
