However, the traditional Proper Orthogonal Decomposition\u2013Radial Basis Function (POD-RBF) reduced-order algorithm requires significant computational resources and is inefficient when calculating high-dimensional data for coal mine gas pressure fields. To achieve the rapid computation of gas extraction pressure fields, this paper proposes a model reduction method based on deep neural networks (DNNs) and convolutional autoencoders (CAEs). The CAE is used to compress and reconstruct full-order numerical solutions for coal mine gas extraction, while the DNN is employed to establish the nonlinear mapping between the physical parameters of gas extraction and the latent space parameters of the reduced-order model. The DNN-CAE model is applied to the reduced-order modeling of gas extraction flow\u2013solid coupling mathematical models in coal mines. A full-order model pressure field numerical dataset for gas extraction was constructed, and optimal hyperparameters for the pressure field reconstruction model and latent space parameter prediction model were determined through hyperparameter testing. The performance of the DNN-CAE model order reduction algorithm was compared to the POD-RBF model order reduction algorithm. The results indicate that the DNN-CAE method has certain advantages over the traditional POD-RBF method in terms of pressure field reconstruction accuracy, overall structure retention, extremum capture, and computational efficiency.<\/jats:p>","DOI":"10.3390\/info15110733","type":"journal-article","created":{"date-parts":[[2024,11,19]],"date-time":"2024-11-19T09:30:25Z","timestamp":1732008625000},"page":"733","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Reduced-Order Model of Coal Seam Gas Extraction Pressure Distribution Based on Deep Neural Networks and Convolutional Autoencoders"],"prefix":"10.3390","volume":"15","author":[{"given":"Tianxuan","family":"Hao","sequence":"first","affiliation":[{"name":"College of Safety Science and Engineering, Henan Polytechnic University, Jiaozuo 454000, China"},{"name":"State Key Laboratory Cultivation Base for Gas Geology and Gas Control, Henan Polytechnic University, Jiaozuo 454000, China"},{"name":"State Collaborative Innovation Center of Coal Work Safety and Clean-Efficiency Utilization, Jiaozuo 454000, China"}]},{"given":"Lizhen","family":"Zhao","sequence":"additional","affiliation":[{"name":"College of Safety Science and Engineering, Henan Polytechnic University, Jiaozuo 454000, China"},{"name":"State Key Laboratory Cultivation Base for Gas Geology and Gas Control, Henan Polytechnic University, Jiaozuo 454000, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8621-1401","authenticated-orcid":false,"given":"Yang","family":"Du","sequence":"additional","affiliation":[{"name":"College of Safety Science and Engineering, Henan Polytechnic University, Jiaozuo 454000, China"},{"name":"State Key Laboratory Cultivation Base for Gas Geology and Gas Control, Henan Polytechnic University, Jiaozuo 454000, China"}]},{"given":"Yiju","family":"Tang","sequence":"additional","affiliation":[{"name":"School of Municipal and Environmental Engineering, Henan University of Urban Construction, Pingdingshan 467036, China"}]},{"given":"Fan","family":"Li","sequence":"additional","affiliation":[{"name":"College of Safety Science and Engineering, Henan Polytechnic University, Jiaozuo 454000, China"},{"name":"State Key Laboratory Cultivation Base for Gas Geology and Gas Control, Henan Polytechnic University, Jiaozuo 454000, China"}]},{"given":"Zehua","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Safety Science and Engineering, Henan Polytechnic University, Jiaozuo 454000, China"},{"name":"State Key Laboratory Cultivation Base for Gas Geology and Gas Control, Henan Polytechnic University, Jiaozuo 454000, China"}]},{"given":"Xu","family":"Li","sequence":"additional","affiliation":[{"name":"College of Safety Science and Engineering, Henan Polytechnic University, Jiaozuo 454000, China"},{"name":"State Key Laboratory Cultivation Base for Gas Geology and Gas Control, Henan Polytechnic University, Jiaozuo 454000, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"437","DOI":"10.1016\/j.jngse.2016.03.027","article-title":"Recent developments in coal mine methane extraction and utilization in China: A review","volume":"31","author":"Zhou","year":"2016","journal-title":"J.
