Combined with the detection technology of goaf, a three-dimensional digital model of water storage space is constructed to reduce the difficulty of calculation of water storage space in traditional caving mining, so as to accurately obtain the three-dimensional shape, spatial position and actual boundary of goaf, calculate the volume and roof area of goaf, and effectively realize the three-dimensional precise detection of goaf. Based on the digital image method, combined with similar material simulation experiments, a three-dimensional model of water storage space in goaf is constructed to quantitatively reveal the spatial and temporal evolution characteristics of water storage space. The dynamic instability characteristics of water storage space in caving mining under the influence of roof caving, rock compaction and water-rock interaction are analyzed, and the evolution process of water storage space in caving mining under the combined action of pressure bearing and water pressure is revealed. The results show that the application of digital comprehensive technology can effectively analyze the spatial form of goaf and quantitatively reveal the temporal and spatial evolution law of water storage space. The research results are of great significance for the accurate calculation of underground reservoir water storage space, the analysis of water storage space evolution and the study of overburden stability.

mining, and the invisibility of goaf leads to the difficulty of accurate calculation of water storage space, this paper proposes a comprehensive technical method for the digitization of spatial form of goaf in coal mine. Combined with the detection technology of goaf, a three-dimensional digital model of water storage space is constructed to reduce the difficulty of calculation of water storage space in traditional caving mining, so as to accurately obtain the three-dimensional shape, spatial position and actual boundary of goaf, calculate the volume and roof area of goaf, and effectively realize the three-dimensional precise detection of goaf. Based on the digital image method, combined with similar material simulation experiments, a three-dimensional model of water storage space in goaf is constructed to quantitatively reveal the spatial and temporal evolution characteristics of water storage space. The dynamic instability characteristics of water storage space in caving mining under the influence of roof caving, rock compaction and water-rock interaction are analyzed, and the evolution process of water storage space in caving mining under the combined action of pressure bearing and water pressure is revealed. The results show that the application of digital comprehensive technology can effectively analyze the spatial form of goaf and quantitatively reveal the temporal and spatial evolution law of water storage space. The research results are of great significance for the accurate calculation of underground reservoir water storage space, the analysis of water storage space evolution and the study of overburden stability.\u003c/p\u003e","manuscriptTitle":"Water storage space calculation and changes in coal mine underground reservoir","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-12-01 22:24:20","doi":"10.21203/rs.3.rs-8194832/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Revision requested","date":"2026-03-16T09:30:04+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2026-03-13T14:31:55+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2026-03-13T14:26:50+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2026-03-07T08:11:22+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2026-03-06T01:59:48+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"78687606901920967796836723823585431021","date":"2026-03-05T01:44:56+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"326543263743432554063833511400481236401","date":"2026-03-04T06:54:14+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"21468376176581349633625221382911866792","date":"2026-03-04T01:43:36+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"51794886487423563420905201946498933367","date":"2026-03-03T00:45:59+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2026-02-28T13:14:42+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"205520142215606622163982061771424167889","date":"2026-02-28T12:55:32+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2026-01-12T06:45:59+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"245098306817361617024506201754553194749","date":"2025-12-30T01:59:47+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2025-11-27T08:49:53+00:00","index":"","fulltext":""},{"type":"editorInvited","content":"","date":"2025-11-26T06:20:55+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2025-11-25T05:29:52+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2025-11-25T05:28:16+00:00","index":"","fulltext":""},{"type":"submitted","content":"Scientific Reports","date":"2025-11-24T14:25:56+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"scientific-reports","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":false,"externalIdentity":"scirep","sideBox":"Learn more about [Scientific Reports](http://www.nature.com/srep/)","snPcode":"","submissionUrl":"","title":"Scientific Reports","twitterHandle":"","acdcEnabled":true,"dfaEnabled":true,"editorialSystem":"stoa","reportingPortfolio":"Scientific Reports","inReviewEnabled":true,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"239870f3-623a-4303-95e8-0aea29b4aaa2","owner":[],"postedDate":"December 1st, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"under-review","subjectAreas":[{"id":58699567,"name":"Physical sciences/Energy science and technology"},{"id":58699568,"name":"Physical sciences/Engineering"},{"id":58699569,"name":"Earth and environmental sciences/Solid earth sciences"}],"tags":[],"updatedAt":"2026-05-02T03:53:18+00:00","versionOfRecord":[],"versionCreatedAt":"2025-12-01 22:24:20","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-8194832","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-8194832","identity":"rs-8194832","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
