Experimental Study on Energy Evolution and Acoustic Emission Characteristics of Fractured Sandstone under Cyclic Loading and Unloading

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

The importance of the research is focused on integrating other techniques and factors into the theory of mechanics of fracture damage, which constitutes a prespective of a particular study.

It would have been ideal to show the impact of the research on sustainability projects and bill and depth of deformation response of rocks under cyclic loading and unloading.

The research carried out has the standard, it would be ideal to show a larger image of figure 1 and a diagram or graph that summarises what has been done and the impacts and applications of importance for the mining project sector.

Response to Reviewer  #1

Dear Reviewer:

We greatly appreciate your time and efforts to improve our manuscript. Those comments are all valuable and very helpful for revising and improving our paper. We have studied comments carefully and have made corrections which we hope meet with approval. The major revisions parts have been marked in red.

 

1：The importance of the research is focused on integrating other techniques and factors into the theory of mechanics of fracture damage, which constitutes a prespective of a particular study.

Response: Thanks for your comments. Many thanks to the experts for recognising this study.

 

2: It would have been ideal to show the impact of the research on sustainability projects and bill and depth of deformation response of rocks under cyclic loading and unloading.

Response: Thanks for your comments. I have read the manuscript carefully and simplified it. I have stated the implications of this study for sustainable development in the conclusion section. The deformation response of rocks under cyclic loading and unloading has been analysed in the paper, while deeper analyses will be further analysed in subsequent studies.

 

3: The research carried out has the standard, it would be ideal to show a larger image of figure 1 and a diagram or graph that summarises what has been done and the impacts and applications of importance for the mining project sector.

Response: Thanks for your comments. I have read the manuscript carefully and simplified it. I have finished modifying Figure 1. And in the introduction section, it explains what are the important impacts and applications of rock cyclic loading and unloading tests to the mining industry.

Please refer to the attached manuscript for specific content changes.

Reviewer 2 Report

Comments and Suggestions for Authors

Dear Authors,

the paper deals a very interesting topic for rock mechanics of sedimentary rocks. The setting out of real lab tests are an added value for geomechanics community.

On the other hand , the novelty of the paper is not clear.

Furthermore, you should explain why you carried out compression tests on cubic specimes (generally are cylider specimens). In the abstract and in the text of the paper you did not highlight that your focus is in prefabbricated fractures with an inclination of 45 °.

Comments on the Quality of English Language

Response: Thanks for your comments. I have read the manuscript carefully and simplified it. I have clearly stated the innovative aspects of this research in the introduction.

Response: Thanks for your comments. I have read the manuscript carefully and simplified it. Square samples, when used with a high-speed camera, facilitate superior monitoring of sandstone deformation, whereas circular samples do not adequately produce a two-dimensional planar deformation image. The presence of a 45° prefabricated fracture has been emphasized in the text, and the article has been revised accordingly.
