Advances in vital‐sign prediction and early‐warning models for underground coal mine workers integrating environmental factors

open access: yesDeep Underground Science and Engineering, EarlyView.
This review synthesizes advances in predicting miners' vital signs by integrating environmental monitoring (dust, temperature, and gas) with physiological data. It highlights multi‐source data fusion techniques and early‐warning models for enhanced occupational safety in underground coal mines.

碎石层和碎石桩组合的地基抗液化能力分析

open access: yesDizhen xuebao
通过物理试验与数值模拟相结合的方法,系统探讨了上覆碎石层、碎石桩及其组合方式对地震引起砂土液化的减轻机制,分析了不同厚度的上覆碎石层与碎石桩对液化的抑制效果。结果表明:上覆碎石层在浅层区域表现出显著的抑制液化效果,有效降低超孔压比;碎石桩则通过提供竖向排水通道,增强土体的排水能力与抗液化性能,其作用效果随着与桩距离的减小及测点深度增加而增强。在深层土体中,碎石桩的有效影响范围明显大于浅层。此外,水平碎石层与竖向碎石桩的组合能够协同作用,既能改善浅层的液化抑制效果,又能增强深层的抗液化能力 ...

Carbon emission assessment of tunnel infrastructures: From construction to operation

open access: yesDeep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

On the Prevention and Control of Geological Disasters and the Utilization of Geological Environment

open access: yesJournal of Innovation and Development
With the rapid development of the social economy, people's awareness of environmental protection is gradually increasing. This is because the probability of geographical disasters occurring in the country is also gradually increasing. People have also begun to pay attention to the prevention of geological disasters and the geological environment ...

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology

open access: yesDeep Underground Science and Engineering, EarlyView.
This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

Investigation on the failure evolution characteristics of surrounding rock in deep cross‐fault roadway: Based on physical model test and numerical simulation

open access: yesDeep Underground Science and Engineering, EarlyView.
This study reveals the failure evolution characteristics of deep cross‐fault roadway surrounding rock under excavation support and periodic weighting. Periodic weighting readily induces fault activation, with the spatial distribution of failed rock masses being controlled by the fault strike and dip.
