In this paper, the coupling relation between different locations of negative pressure of cross-cut drainage and nitrogen injection was investigated. The minefield data collection was carried out by an in situ beam tube system on the intake airway and return airway of the mine goaf. The validated Computational Fluid Dynamics (CFD) model that was secondarily modified by on-site collected data was applied for further research. It is demonstrated that the area of the spontaneous combustion zone generally shows a sharp decline first, then tends to stabilize, and finally has a slight drop and rise with the increasing nitrogen injection time. It is obvious that the location of the negative pressure of cross-cut exerts a significant influence on the optimal nitrogen injection location and time. When the cross-cut is located in the center of the air leakage zone, spontaneous combustion zone, and asphyxiation zone of goaf, the optimal nitrogen injection location and time correspond to the P2 (25 m, 1200 min), P3 (30 m, 120 min), and P4 (35m, 1800 min), respectively. According to the simulation result, the specific relation between the optimal nitrogen injection point N(x) and the distance from the working distance of the cross-cut (x) by Newton interpolation polynomial analysis was figured out and verified that N(x) = 24.70808 + 0.293356x \u2013 0.001436x2. It is hoped that the result can provide scientific guidance for coal mine fire prevention and control with nitrogen injection.<\/jats:p>","DOI":"10.1021\/acsomega.0c06222","type":"journal-article","created":{"date-parts":[[2021,3,17]],"date-time":"2021-03-17T18:42:08Z","timestamp":1616006528000},"page":"8189-8198","source":"Crossref","is-referenced-by-count":15,"title":["Coupling Relation between the Location of Cross-Cut\nNegative Pressure and Injecting Nitrogen into Coal Mine Goaf"],"prefix":"10.1021","volume":"6","author":[{"given":"Liangzhou","family":"Chen","sequence":"first","affiliation":[{"name":"China University of Mining and Technology , , ,","place":["Xuzhou, China, 221116"]},{"name":"China University of Mining and Technology , , ,","place":["Xuzhou, China, 221116"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8624-891X","authenticated-orcid":true,"given":"Xuyao","family":"Qi","sequence":"additional","affiliation":[{"name":"China University of Mining and Technology , , ,","place":["Xuzhou, China, 221116"]},{"name":"China University of Mining and Technology , , ,","place":["Xuzhou, China, 221116"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yadong","family":"Li","sequence":"additional","affiliation":[{"name":"China University of Mining and Technology , , ,","place":["Xuzhou, China, 221116"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haihui","family":"Xin","sequence":"additional","affiliation":[{"name":"China University of Mining and Technology , , ,","place":["Xuzhou, China, 221116"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhongqiu","family":"Liang","sequence":"additional","affiliation":[{"name":"CCTEG Shenyang Research Institute , ,","place":["Shenyang, China, 110000"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2021,3,17]]},"reference":[{"key":"2026081414142145600_cit1","doi-asserted-by":"publisher","first-page":"22502","DOI":"10.1021\/acsomega.0c03108","article-title":"Characteristics for\nOxygen-Lean Combustion and Residual Thermodynamics in Coalfield-Fire\nZones within Axial Pressure","volume":"5","author":"Xu","year":"2020","journal-title":"ACS Omega"},{"key":"2026081414142145600_cit2","doi-asserted-by":"publisher","first-page":"20618","DOI":"10.1021\/acsomega.0c02884","article-title":"Thermodynamic Model\nand Kinetic Compensation Effect of Spontaneous\nCombustion of Sulfur Concentrates","volume":"5","author":"Xiang","year":"2020","journal-title":"ACS Omega"},{"key":"2026081414142145600_cit3","doi-asserted-by":"publisher","first-page":"33347","DOI":"10.1021\/acsomega.0c05172","article-title":"Spontaneous Combustion\nCharacteristics of Wetting Coal under Different Prepyrolysis Temperatures","volume":"5","author":"Wang","year":"2020","journal-title":"ACS Omega"},{"key":"2026081414142145600_cit4","doi-asserted-by":"publisher","first-page":"120007","DOI":"10.1016\/j.fuel.2020.120007","article-title":"Piezoelectric effect\nand ignition properties of coal mine roof sandstone\ndeformation and fracture","volume":"290","author":"Li","year":"2021","journal-title":"Fuel"},{"key":"2026081414142145600_cit5","doi-asserted-by":"publisher","first-page":"27607","DOI":"10.1021\/acsomega.0c04161","article-title":"Effects of Moisture and Associated\nPyrite on the Microstructure\nof Anthracite Coal for Spontaneous Combustion","volume":"5","author":"Wang","year":"2020","journal-title":"ACS Omega"},{"key":"2026081414142145600_cit6","doi-asserted-by":"publisher","first-page":"105739","DOI":"10.1016\/j.enggeo.2020.105739","article-title":"Experimental\nstudy on changes of\npore structure and mechanical properties of sandstone after high-temperature\ntreatment using nuclear magnetic resonance","volume":"275","author":"Li","year":"2020","journal-title":"Eng.
