    Numerical Simulation Study on Gas Migration Patterns in Ultra-Long Fully Mechanized Caving Face and Goaf of High Gas and Extra-Thick Coal Seams by Huaming An, Ruyue Gong, Xingxing Liang, Hongsheng Wang

    Published 2024-12-01
    “…The purpose of this study is to understand the law of gas migration in the goaf and reduce the gas on the working face. Taking the N2105 working face of the coal mining industry as the research object, the mathematical model of gas seepage in the goaf was established based on the percolation theory of porous media, and the model was solved. …”

    Mechanical Characterization of Nano-SiO₂-Reinforced Epoxy Sandwich Composites With 3D Rayon Graphite Felt Core and Woven Carbon Fiber Face Sheets by Zahraa Jalood Nayyef, Nabil Kadhim Taieh, Ammar A. Beddai, Ying Li, Xi Liu, Adil Elrayah

    Published 2025-01-01
    “…This study aims to develop composites with 3, 5, and 7 layers of woven carbon fibers (WCFs) layered on 3D rayon-based graphite felt (3D RGF) as the core of the sandwich composites. Using WCFs as face sheet layers increases flexural strength and modulus. …”
