    Article
    Open Access
    As society moves towards decarbonisation, it is important to assess the hydromechanical behaviour of binders that could offer a low-carbon alternative to Portland cement in ground improvement technologies. This work considers ...
  • Mining footprint of the underground longwall caving extraction method: a case study of a typical industrial coal area in China 

    Liu, Hengfeng; Wang, Yanjun; Pang, Shun; Wang, Xinfu; He, Jianguo; Zhang, Jixiong; Rodríguez Dono, Alfonso (Elsevier, 2022-03)
    Article
