Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b)  CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 1-8 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA  35 U.S.C. 112, the applicant), regards as the invention.
With regard to claim 1, in step 1, it is unclear what “analyzing a lithology of the surrounding rock” is defining. It is unclear how the rock is analyzed and what parameter are analyzed as the limitation is vague. The metes and bounds of the claim cannot be ascertained.
With regard to claim 1, in step 2, it is unclear which portion is damaged (i.e. existing roadway; surrounding rock; etc.). The meres and bounds of the claim cannot be ascertained.
With regard to claim 1, in step 2, it is unclear how the unstable confining pressure bearing characteristics are determined no what defines unstable. The meres and bounds of the claim cannot be ascertained.
With regard to claim 2, it is unclear what applicant is intending to claim by “utilizing a propagation law of artificially excited seismic waves in different elastic strata”. The metes and bounds of the claim cannot be ascertained.
With regard to claim 3, it is unclear what applicant is intending to claim by “using geophysical exploration technology”. Such technology is not described within the specification and the metes and bounds of the claim cannot be ascertained.
With regard to claim 4, it is unclear what applicant is intending to claim by “Model MSGLW-500/22”. The metes and bounds of the claim cannot be ascertained.
Allowable Subject Matter
Claims 1-8 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action.
The following is a statement of reasons for the indication of allowable subject matter: the cited prior art, either alone or in any reasonable combination, fails to teach or suggest all the limitations of the independent claim(s).  Carbon storage underground is known such as that taught by Tian et al. (CN 113217100 A). Placing support formwork with anchor bolts and cables is known such as that taught by Mulvoy et al. (2020/0263542). Surveying surrounding rock is known such as that taught by Ernst (4,537,062). However, the cited prior art lacks the injecting supercritical carbon dioxide into the slurry in combination with the structural details of the formwork and slurry as required by the independent claim(s) and it would not have been obvious to one of ordinary skill in the art at the time the invention was filed to modify the prior art to achieve applicant’s invention without the benefit of hindsight and applicant’s own disclosure.
