Dynamic p rediction  model of spontaneous combustion risk  in goaf  based on improved CRITIC-G2-TOPSIS method and its application

PLOS ONE

Dear Dr. wang,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

ACADEMIC EDITOR:

1) Why you have used G2 method for determining criteria weights? Why not BWM, FUCOM or Level Based Weight Assessment (LBWA) methods? These methods should be discussed. The authors need to discuss their contributions compared to those in related papers.  The authors must clearly discuss the significance of the research problem in the first section.

2) How this modification of CRITIC method is better than the following modification https://doi.org/10.31181/dmame2003149z . This should be discussed in the manuscript.

Please submit your revised manuscript by Sep 13 2021 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org. When you're ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.

Please include the following items when submitting your revised manuscript:

• A rebuttal letter that responds to each point raised by the academic editor and reviewer(s). You should upload this letter as a separate file labeled 'Response to Reviewers'.
• A marked-up copy of your manuscript that highlights changes made to the original version. You should upload this as a separate file labeled 'Revised Manuscript with Track Changes'.
• An unmarked version of your revised paper without tracked changes. You should upload this as a separate file labeled 'Manuscript'.

If you would like to make changes to your financial disclosure, please include your updated statement in your cover letter. Guidelines for resubmitting your figure files are available below the reviewer comments at the end of this letter.

If applicable, we recommend that you deposit your laboratory protocols in protocols.io to enhance the reproducibility of your results. Protocols.io assigns your protocol its own identifier (DOI) so that it can be cited independently in the future. For instructions see: http://journals.plos.org/plosone/s/submission-guidelines#loc-laboratory-protocols. Additionally, PLOS ONE offers an option for publishing peer-reviewed Lab Protocol articles, which describe protocols hosted on protocols.io.

Reviewer #1: Spontaneous combustion of residual coal in goaf is one of the main disasters that affect the safety production of coal mine. It often leads to serious coal resources damage and casualties. Under some special conditions, it can also induce gas explosion and other major malignant accidents. In this paper, considering the existing problems in the risk prediction of spontaneous combustion of residual coal in goaf during the dynamic advancing process of working face, aiming at the shortcomings of the previous established risk prediction model of spontaneous combustion in goaf, a dynamic prediction model of spontaneous combustion in goaf based on improved CRITIC-G2-TOPSIS is proposed, which is a relatively new method of coal spontaneous combustion disaster prediction. It has certain theoretical and engineering application value for revealing the spontaneous combustion characteristics of residual coal in goaf and preventing and controlling such accidents, however, the author still needs to pay attention to the following problems and suggestions:

1.The introduction of this paper can further elaborate the research progress of CRITIC method in the prediction of spontaneous combustion of residual coal in goaf.

2.How to determine the value range of evaluation grade of spontaneous combustion of gob residual coal in Section 3.2 of this paper?

3.In section 1.4 of the paper, "the determination of dynamic weight" is not clear about whether the 15 secondary indicators are used to determine the weight dynamically.

4.This paper studies the dynamic prediction of goaf spontaneous combustion risk based on improved CRITIC-G2-TOPSIS, how is it achieved?

5.In the conclusion of the paper, "3) The weights of the evaluation indexes obtained using the dynamic comprehensive weighting method show that the degree of influence of each index on spontaneous goaf combustion is different. The primary and secondary factors affecting the spontaneous goaf combustion risk of working face 1303 in the Jinniu Coal Mine are as follows: ...", which is best explained in the paper.

6.In Section 4.3 of this paper, the dynamic evaluation results of G2-TOPSIS are suggested to be transformed from vector product to column vector transpose or to give the calculation results directly.

7.There are a lot of articles using mathematical prediction model to evaluate the risk of spontaneous combustion in goaf. Where is the innovation of the paper?

8.By establishing a dynamic prediction model of goaf spontaneous combustion risk based on improved CRITIC-G2-TOPSIS, this paper makes a dynamic analysis on the spontaneous combustion risk of residual coal in 1303 working face of Jinniu coal mine. Why do you choose this model and what are its advantages? Please specify.

9.The latest references related to the content of the article are few. It is recommended to increase the number of references in the past three years.

10.Please modify the acknowledgment content of the paper. Acknowledgements are generally to thank the project sponsors and colleagues who have contributed to the experiment and writing of the paper but are not the author.

Reviewer #2: Thank you for inviting me as a reviewer for the paper titled Dynamic prediction model of spontaneous combustion risk in goaf based on improved CRITIC-G2-TOPSIS method and its application. This topic is important for investigation, and I am giving support to the authors. The paper has well structure. For the paper to be accepted, certain refinements need to be made:

- Literature analysis needs to be improved. Add another 10-15 papers of more recent date (period 2019-2021), such as:

o https://doi.org/10.31181/dmame2003149z

o https://doi.org/10.31181/rme200101162k

o doi.org/10.22190/FUME200305031A

- Compare the results with other methods (for example: VIKOR, MABAC, DEMATEL, etc.).

- Systematize the advantages and limitations of your research study.

- Add future research in conclusion.
