Thanks for this study.
The introduction can be improved by giving some examples of the problem in the real live with photos and statistics showing this study can improve the efficiency of the bulk solid stacking significantly.
In chapter 2 you propose a strategy for stacking (figure 1), is it the only possibility? Other scenarios have also been studied?
Explain more (lines 186-193) about how these formulas have been stablished. What is an acceleration time? is it in seconds or in hours?
More details about the measurement methods in the experiment is needed.

The motivation of the research is weak; it is necessary to emphasize more the reason why all this research was done.
After all, it is optimal to load as much as it can carry (by weight) or as much as it fits (by volume) into a ship, truck, wagon, or any means of transport.
In Figure 3, the same grain sizes of different materials should have been placed under each other so that the resulting shape could be compared.
In lines 139 to 149, you describe numerical integration methods. Just replace these ten lines with one short sentence. "With the help of numerical integration methods, we determined the size of the area under the curve, and by rotating it, we determined the volume of the body with an accuracy of ????."
I can't quite agree with the statements in chapter 3. The floor plan will be circular only at the beginning of the tie-in. After several cycles, the floor plans of neighbouring stockpilers will touch and influence each other. The circular floor plan will gradually change to a square one. The resulting volume will have the shape of a prism with a quasi-conical cap (perhaps more like a parabolic cap - the result of pouring from a certain height). The body of the stockpilers near the wall will also develop similarly. Only the outer side remains as an arc in the open space.
The literature used is up-to-date but mainly Chinese. They certainly dealt with the issue outside of China.

The present research is interesting, but it should add some literature review work on stacking strategies.
In general more outlines of the research planning are missing.
In 2.3 add some equations that explain the figures.
In part 4. improve the design of experiments and schemes of the procedure.
How they determined that 6 trials are enough
And show the development, golden section algorithm is adopted for the calculation of the bulk solids stockpile at each stacking location

Dear authors, thanks for your effort to improve your paper and give answers to my questions.
