Abstract The propagation process of blasting vibration has always been a difficult problem affecting the stability high slopes in open-pit mines. Taking Jianshan Phosphorus Mine as research background, combined with engineering geological investigation, field test, monitoring, numerical simulation technology, and theoretical analysis, three-dimensional dynamic adjacent slope after was systematically studied. In our study, small-diameter buffer shock-absorbing technology near proposed, which...
Natural flaws containing fillings strongly affect the mechanical properties and failure process of rocks in practical engineering. In this work, uniaxial compression tests are performed on filled unfilled red sandstone specimens two parallel dentate flaws. Two monitoring technologies––acoustic emission (AE) high-speed camera––are employed to record cracking flawed rocks. The effects filling ligament angles analyzed. relationship between AE parameters stress–strain curves is established order...
Deep learning has performed well in feature extraction and pattern recognition been widely studied the field of fault diagnosis. However, practical engineering applications, lack sample size limits potential deep Moreover, practice, it is usually necessary to obtain multidimensional information (such as localization quantification), while current methods mostly only provide single-dimensional information. Aiming at above problems, this paper proposes an Attention-based Multidimensional Fault...
With the ending of deep-concave open-pit phosphorite extractions and gradual exhausting shallow mineral resources, stoping seams has entered or will enter into underground mining. Particularly for excavating slightly inclined thin medium-thick orebodies, roof surface control under different mining methods is crucial safe efficient exploitations. In this study, study area located in Kunyang Phosphorite Mine characterized by deposits. Based on occurrence conditions, orebody thickness, dip...
Abstract The numerical approach is a vital means for evaluating the stability of flawed rocks. In this paper, extended non‐ordinary state‐based peridynamics (NOSB‐PD) theory employed to simulate fracture process rocks containing two pre‐existing flaws. Two stress criteria, including maximum tensile criterion and Mohr–Coulomb criterion, are implemented into NOSB‐PD method respectively judge shear failure rock materials. effects inclination angles ligament on crack initiation coalescence modes...
In order to solve frost damage problems in cold-region tunnels, a new sustainable energy based freeze proof method for tunnel drainage system is proposed. The applied Tianshan Shengli Tunnel, China as case study show the concept and details of ground heat exchangers (GHEs) including calculation active heating length maximum load, design extraction cross tunnel, segmented method. Long-term performance GHEs also fully discussed. Multi-field simulations are performed achieve corresponding...
Predictive health management (PHM) plays a pivotal role in the maintenance of contemporary industrial systems, with evaluation state (SOH) and prediction remaining useful life (RUL) constituting its central objectives. Nevertheless, existing studies frequently approach these tasks isolation, overlooking their interdependence, predominantly concentrate on single-condition settings. While Transformers have demonstrated exceptional performance RUL prediction, substantial parameter requirements...
Geopolymer is a new type of synthesized aluminosilicate material. Compared with ordinary Portland cement, it has better fire resistance and durability, more environmentally friendly. In this paper, high-strength metakaolin-based geopolymer composite (HMGC) been developed by utilizing quartz powder steel fibers. The optimization compositions effect curing temperatures (from ambient temperature to 90 °C) on the strength performance HMGC studied. optimized 1-day compressive can reach 80 MPa,...
