Degradation mechanism of coal pillars in an underground coal gasification environment: Bearing capacity, pyrolysis behaviour and pore structure
Li, Jian; Bai, Jinwen; Feng, Guorui; Yılmaz, Erol; Han, Yanna; Wang, Zhe; Wang, Shanyong; Wu, Guowei (Elsevier, 2025)Coal pillars are critical supporting structures between underground coal gasification gasifiers. Its bearing capacity and structural stability are severely threatened by high-temperature environments. To elucidate the ... -
Red mud additive effect on fluidity, strength features and microstructure of viable geo-polymer grouting materials
Wu, Guowei; Bai, Jinwen; Yılmaz, Erol; Feng, Guorui; Han, Yanna; Ma, Junbiao (Elsevier, 2025)Being an alkaline solid waste, Bayer red mud (RM) is made during alumina extraction, whereas fly ash (FA) is a byproduct made during aluminum creation. RM-FA based geopolymer grouting materials were prepared for the first ...
