ObjectiveRescue drilling rigs undergo intense vibration at borehole mouths when operating in a confined underground space of coal mines. To address this issue, this study designed a compact multi-directional, passive dyn...

The case study of closely spaced twin tunnels excavated vertically beneath the adjacent Chaoyangmen station in Beijing, China is introduced. The existing subway station is part of the Beijing subway Line 2. The new recta...

ObjectiveCoals are highly sensitive to variations in temperature and pressure conditions. The structural evolution of coal macromolecules, driven by tectono-thermal processes, is the key to understanding coal rank transi...

To study the influence of frequency on the dynamic characteristics of structural soft clay, a series of dynamic triaxial tests based on the two kinds of waveforms and different vibration frequencies are performed. The re...

The Wilcoxon rank sum nonparametric statistical test is introduced to establish an evaluation model for identifying structural domain boundaries in jointed rock masses. A new method for identifying structural domain boun...

3D printing is used to produce different permeability structural surfaces, and rock-like samples are poured by moulds. The tests on permeability of rock-like samples with consecutive and filling fractures are carried out...

A comprehensive structural, petrological, and geophysical study of the 385 ± 2 Ma Devonian El Hornito Pluton (EHP) in the Sierra Grande de San Luis, Argentina, is presented. We establish that the EHP results from the in...

Abstract Thick-hard roof fracturing presents a significant challenge for disaster prevention in longwall mining. This study investigates the 15,311 south working face and develops a mechanical model to analyze energy rel...

The rock-cut heritage of the Kayseri Valleys represents a distinctive vernacular tradition shaped by technological skill, social practices, and environmental adaptation. These systems, evolving from carved spaces to maso...

Due to the green and environmental protection operation mode, the tram is leading the transportation industry into sustainable development in China. According to the structural characteristics and engineering properties ...

During tunnel construction using the drilling and blasting method, layered jointed rock masses often pose engineering challenges such as over- and under-excavation of the crown and working face. The authors addressed the...

Under the framework of bounding surface plasticity and critical state concept, by introducing the disturbed state concept for hardening variables of elastic behavior, structured yield surface, structured bonding adhesive...

In practical projects, structural fracture often undergoes complex stresses. The studies on the fracture mechanism of mixed mode cracks are of important theoretical significance and practical implication. Based on the mi...
