Characterization of early age behavior of cemented paste backfill through the magnitude and frequency spectrum of ultrasonic P-wave
Yan, Baoxu; Zhu, Wancheng; Hou, Chen; Yılmaz, Erol; Saadat, Mahdi (Elsevier Sci Ltd, 2020)Cemented paste backfill (CPB) is broadly used for underground backfilling, improving the mechanical performance through the modification of its composition and, therefore, its microstructure and characteristics. in order ... -
Goaf instability in an open pit iron mine triggered by dynamics disturbance: a large-scale similar simulation
Yan, Baoxu; Jia, Hanwen; Yang, Zhen; Yılmaz, Erol; Liu, Honglei (Taylor & Francis Ltd., 2023)The stability of concealed goafs in open-pit mines under the influence of blasting disturbances is directly related to successful mining production. Based on large-scale similar simulations, this study steadily analyses ... -
Identifcation of goaf instability under blasting disturbance using microseismic monitoring technology
Jia, Hanwen; Yan, Baoxu; Yang, Zhen; Yılmaz, Erol (Springer, 2023)Micro-seismic (MS) technique can be used to appreciate rock failure process and severity of damage by quantifying micro-earthquakes in terms of time, location, grade, and energy release. Based on 3D laser detection and ... -
A large goaf group treatment by means of Mine Backfill Technology
Jia, Hanwen; Yan, Baoxu; Yılmaz, Erol (Hindawi, 2021)There are few studies on the management methods of large-scale goaf groups per the specific surrounding rock mass conditions of each goaf. This paper evaluates comprehensively the stability of the multistage large-scale ... -
Numerical investigation of creeping rockmass interaction with hardening and shrinking cemented paste backfill
Yan, Baoxu; Jia, Hanwen; Yılmaz, Erol; Lai, Xingping; Shan, Pengfei; Hou, Chen (Elsevier, 2022)Revealing the interaction mechanism between the time-dependent deformation of rockmass and hardening backfill are important for successful mining design. Based on laboratory tests and numerical simulation, a framework has ... -
Numerical study on microscale and macroscale strength behaviors of hardening cemented paste backfill
Yan, Baoxu; Jia, Hanwen; Yılmaz, Erol; Lai, Xingping; Shan, Pengfei; Hou, Chen (Elsevier, 2022)Computer aided optimization of cement-based materials proportion can accurately quantify the accompanying microstructure evolution, material composition, and the mechanical properties changes. However, no relevant research ... -
A solution to the time-dependent stress sistribution in suborbicular backfilled stope interaction with creeping rock
Yan, Baoxu; Lai, Xingping; Jia, Hanwen; Yılmaz, Erol; Hou, Chen (Hindawi, 2021)The creep behavior of deep weak rock masses is important due to an underground opening. Appreciating the nature and source of these deformations requires the knowledge of rock mass and ground support interaction. The ...
