Analysis of tensile mechanical characteristics of fibre reinforced backfill through splitting tensile and three-point bending tests
Xue, Gaili; Yılmaz, Erol; Feng, Guorui; Cao, Shuai (Taylor & Francis Ltd., 2021)The cut-and-fill mining method is used in metalliferous mines thanks to backfilling instead of ore pillars. However, the stability of the artificial cemented tailings backfill (CTB) roof is one of the key influencing factors ... -
Assessment of rheological and sedimentation characteristics of fresh cemented tailings backfill slurry
Cao, Shuai; Xue, Gaili; Yılmaz, Erol; Yin, Zhenyu (Taylor & Francis Ltd, 2020)Unreasonable choice of solid content (SC) and cement-to-tailings ratio (c/t), including pipeline networking system, will lead to some pipeline problems, such as blockage, wear, and rupture. Hence, this study deals with the ... -
Bending behavior and failure mode of cemented tailings backfill composites incorporating different fibers for sustainable construction
Xue, Gaili; Yılmaz, Erol; Feng, Guorui; Cao, Shuai (Elsevier, 2021)Mechanical characteristics of cementitious materials with fiber reinforcement are different from non reinforced cementitious materials. The influence of fiber type and content, solid content, and cement to-tailings ratio ... -
CT scanning of internal crack mechanism and strength behavior of cement-fiber-tailings matrix composites
Cao, Shuai; Yılmaz, Erol; Yin, Zhenyu; Xue, Gaili; Song, Weidong; Sun, Lijuan (Elsevier Ltd, 2021)This paper deals the relationship between compressive strength and internal crack formation (e.g., crack width and volume) of cement-fiber-tailings matrix composites (CFTMC) using an industrial computed tomography system ... -
Fiber length effect on strength properties of polypropylene fiber reinforced cemented tailings backfill specimens with different sizes
Xue, Gaili; Yılmaz, Erol; Song, Weidong; Cao, Shuai (Elsevier Sci Ltd, 2020)The strength properties of cemented tailings backfill (CTB: an engineered mix of processing tailings, hydraulic binder and mixing water) is strongly affected by its structural integrity. However, our understanding of the ... -
Progress and prospects of mining with backfill in metal mines in China
Xue, Gaili; Yılmaz, Erol; Wang, Yongding (Springer, 2023)Mining is the foundation of modern industrial development. In the context of the "carbon peaking and carbon neutrality" era, countries have put forward the development strategy of "adhering to the harmonious coexistence ... -
Reinforcement effect of polypropylene fiber on dynamic properties of cemented tailings backfill under SHPB impact loading
Xue, Gaili; Yılmaz, Erol; Feng, Guorui; Cao, Shuai; Sun, Lijuan (Elsevier, 2021)Dynamic loads such as blasting may lead to diverse levels of failure in cemented tailings backfill (CTB) under diverse strain rates and frequency spectral amplitudes. Hence, changes in dynamic properties of filling due to ... -
Strength, acoustic, and fractal behavior of fiber reinforced cemented tailings backfill subjected to triaxial compression loads
Xue, Gaili; Yılmaz, Erol (Elsevier, 2022)Overall, solid materials like CTB (i.e., cemented tailings backfill) give out low-level seismic signals as they are under stress in underground mining applications involving ground control, rock burst, and coal bump ... -
Utilizing concrete pillars as an environmental mining practice in underground mines
Cao, Shuai; Xue, Gaili; Yılmaz, Erol; Yin, Zhenyu; Yang, Fudou (Elsevier Ltd, 2021)Ground control is an integral element of mine design and worker safety. The use of concrete pillars for underground mines is of paramount importance to maintaining the economic and operational security of structures. This ...
