Evaluating the Geo-Environmental Conditions within a Working Face Using a Hybrid Intelligent Optimization Model
and Wenhua Jiao 1
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThe subject of this paper is an innovative method for identifying geo-environmental anomalies in a working face panel using electromagnetic tomography. The anomalies are characterised by a change in the absorption coefficient of the electromagnetic wave. The main research problem investigated concerns the use of the electromagnetic tomography method in underground mine workings where the grid of electromagnetic rays is irregular. This causes instability in the present tomographic inversion algorithms for electromagnetic waves.
The use of EMT technology to provide a more precise, stable and reliable tomographic inversion algorithm is a crucial issue in the field of geo-environmental anomaly identification, as it makes it possible to solve the problem of determining the initial model for a traditional tomographic inversion algorithm. An original and transparently described way of reconstructing geo-environmental conditions from the recorded electromagnetic ray is the hybrid intelligent optimisation model MPGA-SIRT. Expert combination of the multiple population genetic algorithm (MPGA) and the simultaneous reconstruction method (SIRT) has produced a programme with considerable accuracy and stability in the inversion process. These constitute the great significance and scientific impact of the article. This is because the effectiveness of most commonly used tomographic inversion methods is dependent on the appropriate initial model selection.
The advantageous features of the programme (MPGA-SIRT) have been confirmed by computer and in-situ test results. The identified anomalies in the absorption coefficient of the electromagnetic wave were compared with information on the disturbances in the seam obtained from the geological investigation. Relatively good compliance has been obtained.
Presented conclusions are related to the basic scientific problem being solved. They are well justified in the body of the paper. This is evidenced by a comparison of the objective function convergence results obtained for the MPGA-SIRT, SGA-SIRT and SIRT algorithms.
The paper is written in an easy-to-understand format and with high standards of presentation. References are appropriate and correctly used in the text. I believe that a publication on the application of the MPGA-SIRT algorithm to reconstruct geo-environmental anomalies using grid-limited electromagnetic tomography caused by the location of underground workings surrounding a working face will be of interest to readers of the journal Applied Sciences. The importance of the article is, in my opinion, high, as further research into the described MPGA-SIRT algorithm will enable more precise identification of rock mass properties than before, and therefore safer mining of mineral deposits.
Detailed remarks:
Line 266: Table 1 containing the initial parameters of the MPGA programme is not included in the manuscript. Table 1 in line 389 contains other data discussed in lines 382-388.

Reviewer 3 Report
Comments and Suggestions for AuthorsThe manuscript presents the development and detailed analysis of the possibilities of a new hybrid intelligent algorithm for the assessment of geoecological conditions within a closed underground pit.
The efficiency and novelty of the proposed method lies in the combination of two algorithms with at the same time field tests.
Therefore, the work has an obvious scientific novelty, since the presented hybride algorithm has both theoretical and experimental value at the same time.
The topic of the work is relevant
The research methodology presented in the work is clear and the study results are completely based on it.
The conclusions are fully reflected on the basis of the obtained research results.
The work is interesting for the reader and can be useful both for future theoretical and practical applications.
The used list of cited literature is quite extensive, but half of it (22 studies) is quite old (their age is 5 years or older).
Tips for improving your manuscript:
1. It would be nice to significantly increase the number of modern studies for review.
2. For a clearer understanding of the graphic material, it would be good to write the axes of the diagrams in the figures in lines 345, 347, 417, 419, 422 with letters X , Y.
3. For a better design, it may be worth specifying the dimension directly in Table 3.
4. In line 354, figure 5 should be better to signe without using non-English characters.
5. The work certainly deserves to contain a paragraph highlighting the perspective of the future development of these studies.
Comments on the Quality of English LanguageThe text of the study reads well but there are a few of terminological ambiguities, including those probably related to certain obstacles in the translation.
1. The term "roof" in line 9 is not entirely clear .
2. In line 354, Fig.5 contains captions of non-English origin
