However, the ability of bolts and anchor cables to withstand transverse shear decreases with the prestress level, jeopardizing mining safety. This study proposed a technical solution to this problem featuring anchor cables enclosed in an axisymmetrical tube with a C-shaped cross-section (ACC), which are highly prestressed and can withstand high transverse shear. The ACC mechanical performance was tested in the #318 gas extraction roadway of the Shuangliu Coal Mine, China, characterized by extensive deformation under original support conditions. Theoretical analysis, laboratory tests, numerical simulation, and field tests were performed to analyze the shear mechanical properties of the ACC and anchor cables alone. The double shear test results revealed that the proposed ACC scheme increased the transverse shear resistance and stiffness by 10\u201325% and 20\u201340%, respectively. The FLAC3D numerical simulation showed that the roof-and-floor and rib-to-rib convergences decreased by 9.53 and 25.11%, respectively. The area of the stress concentration zone also decreased. Field monitoring showed that the ACC achieved good support performance. During the monitoring period, the maximum roof-and-floor and rib-to-rib displacements were 40 and 49 mm, respectively. The ACC scheme offered adequate shear resistance and effectively controlled surrounding rock deformation in the gas extraction roadway under study, making it applicable to similar engineering scenarios.<\/jats:p>","DOI":"10.3390\/sym15091757","type":"journal-article","created":{"date-parts":[[2023,9,14]],"date-time":"2023-09-14T09:57:56Z","timestamp":1694685476000},"page":"1757","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["A Study of Anchor Cable and C-Shaped Tube Support for the Roadway of Shuangliu Coal Mine"],"prefix":"10.3390","volume":"15","author":[{"given":"Li","family":"Li","sequence":"first","affiliation":[{"name":"School of Mechanics and Civil Engineering, China University of Mining and Technology (Beijing), Beijing 100083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4133-0423","authenticated-orcid":false,"given":"Xiang-Song","family":"Kong","sequence":"additional","affiliation":[{"name":"School of Mechanics and Civil Engineering, China University of Mining and Technology (Beijing), Beijing 100083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Mechanics and Civil Engineering, China University of Mining and Technology (Beijing), Beijing 100083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun-Wei","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Mechanics and Civil Engineering, China University of Mining and Technology (Beijing), Beijing 100083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhi-En","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Mechanics and Civil Engineering, China University of Mining and Technology (Beijing), Beijing 100083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,13]]},"reference":[{"key":"ref_1","first-page":"4133529","article-title":"Stress Evolution Mechanism and Control Technology for Reversing Mining and Excavation under Mining-Induced Dynamic Pressure in Deep Mine","volume":"2022","author":"Wang","year":"2022","journal-title":"Geofluids"},{"key":"ref_2","first-page":"602","article-title":"Research on the anchor cable combined with the c-shaped tube and the mechanical properties","volume":"43","author":"Shan","year":"2022","journal-title":"Rock Soil Mech."},{"key":"ref_3","first-page":"1","article-title":"Seventy years development and prospects of strata control technologies for coal mine roadways in China","volume":"40","author":"Kang","year":"2021","journal-title":"Chin.
