Summary: Impact disturbance and bedding angle significantly affect the mechanical response of sandstone under prestressed loading. A combined 1D static and dynamic loading test system is employed to investigate the compression behavior of sandstone at different bedding angles. The results show that strain rebound easily occurs in high-strength sandstone under low impact pressure, and the peak strength of sandstone is positively correlated with the impact pressure. Additionally, the impact pressure influences the crack growth rate of sandstone.

Summary: This study investigated the response of fully-clamped UHMWPE plates to combined blast and fragment impacts through experimental and numerical simulations. The results showed that combined blast and fragment loading led to increased plate deflection. The position of the fragment-foam projectile (FSP) in the foam sabot significantly affected the ballistic resistance of the UHMWPE target, and the target's ballistic resistance was superior when subjected to simultaneous blast loading and fragment impact compared to fragment impact alone.

Summary: In this article, an improved failure mode and effect analysis (FMEA) model is developed by incorporating the concepts of Z-number, rough number (RN), and probabilistic distance measure. The model introduces two new concepts, namely, double upper approximated rough number (DUARN) and granulized Z-number (gZN), and proposes a new scheme for measuring distance between two gZNs. Additionally, a new risk prioritization model, granulized Z-VIKOR, and a scheme for uncertainty assessment using box-plot are proposed. The applicability, effectiveness, and robustness of the proposed model are demonstrated through case studies and comparative analysis, showing its superiority over existing models.

Summary: Efficient underground extraction of thick coal seams requires engineering efforts to be organized based on the rock mechanic conditions of the site, including controlled roof caving and appropriate pillar height selection. Field studies have shown that the presence of competent overlying strata can cause large-scale caving inside the goaf. Fracturing the competent overlying strata can help reduce its strength and achieve controlled strata behavior.

Summary: In this study, a novel approach was proposed to improve occupational safety by combining virtual reality, safety function deployment, inventive problem solving theory, and capital budgeting. The effectiveness of immersive safety training was observed, and a 3D virtual reality environment was created for the training of electric overhead travelling crane operators. The study established relationships between tasks and hazards, hazards and initiating mechanisms, and initiating mechanism and safety interventions using three "House of Safety" models. Capital budgeting was used to select optimal safety interventions based on priority weights. A 15% improvement in safety performance was observed after the training, and technology-based interventions were found to be more important than traditional interventions.

Summary: In recent years, machine learning has been increasingly used in occupational accident research, but there are still challenges in dealing with data uncertainty, unstructured information, and lower prediction power. This study proposes a new methodology to address these challenges by using rough set (RS)-based predictive model and Z-number for rule generation. The proposed method is demonstrated to be effective compared to other state-of-the-art algorithms using benchmark datasets and real-life occupational safety data. Results show that the RS sample-based PSO-ANFIS produces the minimum mean absolute error (MAE) in risk prediction and is the most robust algorithm.

Summary: This study addresses the inefficiency in real-time visualization and user interaction in traditional accident causation models (ACMs) by proposing a virtual reality-based accident causation model (VR-ACM). The proposed model consists of three modules for VR-based modelling and simulation, accident causation analysis, and safety training. Several research issues for VR-ACM are highlighted, and an experimental study with crane operators demonstrates the applicability of the model. VR-ACM serves as a tool for analyzing potential underlying causes of accidents, offering three-dimensional visual analysis, real-time user interactions, and real-time decision-making.
