Exploration Technology of Adverse Geological Body in Karst Development Area Based on Borehole Multi-Source Data
Round 1
Reviewer 1 Report
This paper presents a exploration technology of adverse geological body in karst development area based on borehole multi-source data, which can provide more abundant and reliable exploration data for the fine exploration of geological bodies in the exploration area. This technology is a new and effective exploration method in the engineering geological exploration of karst development areas. The paper is well written and can be accepted for publication after minor revision. Detailed comments are as follows:
(1) In Section 2.1, C0, C1 and C2 in Fig. 3 are not consistent with C0, C1 and C2 described in the article, and need to be checked for accuracy.
(2) The initial letter of “ using the upper and lower conic mirrors with different inclination angles to reflect the 360° image information of the borehole wall into the imaging component. ” is not capitalized.
(3) Some parameters in relation (1)~(4) are not defined, such as R1, α, β.
(4) The PT in relation (5) is inconsistent with the description of the parameter definition PT in the article, which needs to be checked for accuracy.
(5) Some references are long and cannot reflect the current technical level. It is suggested to replace them with references in recent years.
(6) In the case study, three kinds of equipment are used for comprehensive survey. If there are differences in the use order of these equipment, whether the results will be affected.

Reviewer 2 Report
The objective of this paper is setting the theoretical and methodological background for the fine detection technology of adverse geological bodies in karst development areas, which can ensure the safety, stability and economy of the project.
This is an interesting and well-structured paper, which includes all necessary sections (Introduction, Borehole multi-source data acquisition technology, Detection technology of adverse geological bodies, Case analysis, Conclusion) are included. Moreover, most of the sections are divided into several sub-sections, providing detailed descriptions. Furthermore, all Figures and Diagrams are consistent with the analysis described in the manuscript. Regarding the mathematical part, analyzed in the “Borehole multi-source data acquisition technology” and “Detection technology of adverse geological bodies” sections, it is valid and accurately explained. However, some changes should be implemented, which will result in the paper improvement. Particularly:
Lines 13-33: The abstract is satisfactorily structured; however, many details have been included. The abstract should be brief and comprehensive. The additional details can be contained into the manuscript main body (not in the abstract). Please, modify.
Lines 38-64: The first paragraph of the “Introduction” section, which is quite significant for setting the theoretical background of the paper, shows significant bibliographic omissions. In particular, more updated references, related to karst, should be added. Typical papers, in which significant information related to this subject, are contained in the following papers (they can optionally be cited): 1.

Lines 105-123: This paragraph, presenting the paper objectives is vague; I suggest rephrasing it. Please, apply.
Lines 126-143: This is a theoretical part, and it should be supported with more bibliographic references. Please, update the relative references.
Line 144-145: Please, provide Figure 1 in a higher resolution. It contains blur parts in the current form. Moreover, provide a more detailed description in the corresponding caption, please.
Line 162: The Figure 2 caption should be more detailed. Please, modify.
Line 276: Figure 6 should be provided in a higher resolution. Please, apply.
Line 320: Please, correct the title (“Detection technology of adverse geological bodies”).
Line 449: I suggest removing Figure 9, as a satisfactory description is provided in the manuscript. Please, apply.
Line 581: Please, provide a brief description for Figure 15 (a, b and c).
Line 423: The “Conclusions” section should be modified. In the current form, it resembles an abstract rather than conclusions. This section should be comprehensive, while the major findings of the paper should be highlighted. Maybe, numbering of the conclusion remarks could be performed. Please, apply.

Reviewer 4 Report
The optical imaging echnology of boreholes, directional acoustic scanning technology of boreholes and borehole radar technology are involved in the study. The work is comprehensive. The following issues should be addressed before acceptance.
(1) What are the "A", "B", "C" and "D"? More details can be plotted or be illustrated in the main text.
(2) Fig. 6: The distance between the transmitter and receiver, and also the target should be illustrated.
(3) The parameters in the equations should be explained.
(4) Line 556: "Fig. 13 Borehole wall borehole image"->"Fig. 13 Borehole wall in the borehole image".
(5) Fig. 18: What is the meaning of "Unfilled", and also the "filled"? What are the different colors in this figure?
(6) Can the cavity and water be detected?
(7) More recent studies of the borehole technique in the explanation of the damages in rock structures can be reviewed, such as Zhen Zhang, Zhen Li, Gang Xu, et al., Lateral abutment pressure distribution and evolution in wide pillars under the first mining effect, International Journal of Mining Science and Technology, https://doi.org/10.1016/j.ijmst.2022.11.006. The borehole observation was used in the characterization of the damage zones in the deep mining.
(8) Editing needs revisions in Line 68: "such as ... such as ..."
(9) Line 110: a new paragraph can starts with "This paper starts with the fine detection of borehole wall..."
