Abstract ：
To comprehensively investigate the effect of different minimum principal stresses on the stability of straight-wall arched tunnels, the static stress and low-frequency disturbances are applied in true triaxial loading tests, accompanied by acoustic emissions (AE) and internal image monitoring for damage. The results show that (1) increasing the minimum principal stress (along the axial direction of the tunnel) will improve tunnel stability, and (2) during the damage process of straight-wall arched tunnels, whether caused by static stress or low-frequency disturbances, the dissipated energy and AE count had demonstrated identical increasing trends in their numerical values. (3) When the straight-wall arched roadway had been damaged by low-frequency disturbances, the dissipated energy and AE count had increased gradually at first and then surged rapidly upon macroscopic damage, following a trend similar to an exponential function.Please check and confirm that the authors and their respective affiliations have been correctly identified and amend if necessary.We have confirmed the correctness of the authors and their affiliations

Abstract ：
Rock drilling of face 1703 of section 185 of the Ashele Copper Mine was used to study dust migration, control, and reduction during excavation. Fluent numerical simulation and theoretical analysis methods were used to study dust pollution during excavation. An orthogonal experiment was carried out to optimize the ventilation parameters of the excavation face and assess the effect of the main parameters (the cross-section size of the air inlet duct, the location of the end face of the roadway inlet duct and air inlet rate of the excavation face) on dust reduction and control. The experimental results show that the ventilation parameters that were most significant in reducing and controlling the dust pollution were the excavation face air inlet rate. A range analysis showed that the most reasonable ventilation parameters were an air inlet rate of the excavation face of 13 m/s, the location of the end face of the roadway inlet duct of 4 m, and the cross-section size of the air inlet was 0.9 m. A comparison of the original and optimized ventilation schemes showed that the dust pollution in the excavation face and the respiratory area decreased significantly. The effectiveness of the optimized parameters was further checked through field tests. Finally, by dividing the activity areas of underground workers in the roadway and further calculating and analyzing the dust concentration in the breathing area of underground workers based on Python deep data mining, providing theoretical assistance for dust control.

Abstract ：
Unveiling the mechanical and failure characteristics of flawed granite subjected to high-temperature (HT) cycles is essential for assessing the stability of underground engineering. There is limited advanced knowledge of the rock performance under HT cycles even today. To that end, biaxial compression experiments with the simultaneous acoustic emission (AE)-digital image correlation (DIC) monitoring are conducted on flawed granite containing the flaw pairs, with the emphasis on the influences of HT cycles on the mechanical and failure characteristics of flawed granite. Experimental results suggest that the rock strength is increased at 400 °C, regardless of the cycle number, while it is weakened at 600 °C, especially under the thermal cycles. By the coupling analysis of acoustic-optical-mechanical data, the levels of cracking in flawed granite are revealed as the process zone nucleation and quasi-static growth, along with the macrocrack initiation, propagation, and coalescence until the eventual failure, dictated by the stress shielding effect and stress amplification effect. The splitting crack, hook crack, and far-field network crack are reported for the first time. Moreover, the flawed granite at different temperatures transitions from tensile-dominated cracks to mixed tensile-shear (T-S) cracks. Besides, thermal cycling causes rock fatigue damage, and the alternating thermal stress generated by HT cycling promotes the initiation and propagation of microcracks, leading to the development and further intensification of thermally induced fracture. © 2024 Elsevier Ltd

Abstract ：
Given the lack of research on dust pollution diffusion under traditional ore drawing operations in gold mines, Ansys Fluent was used to simulate the flow characteristics of air and dust pollution in the roadway. The results show that the airflow state in the main transport roadway is relatively stable and strong reverse air circulation develops in the ore drawing roadway. Dust is highly concentrated in the ore drawing area and moves to both ends of the roadway. The dust discharge rate on the operation surface is slow, taking 150 s for a single ore drawing operation to meet the requirement of continuous operation. Finally, a new ventilation and dust removal system based on a mist curtain approach and an intelligent damper was designed to maintain the airflow cleanliness required by each operation surface and reduce dirty air series connection, after application testing, the dust reduction effect can reach 72.6 %. © 2024 Elsevier B.V.

Abstract ：
Layered composite rocks (abbreviated as LCRs) are frequently encountered in rock engineering, and it is difficult to predict whether the stress-induced crack propagates through the layers or is contained within a layer when subjected to external loads. There was limited advanced knowledge of the crack propagation mechanism of flawed LCRs because the previous research mainly focused on the single lithologic layer. This study conducts uniaxial compression tests on weaker and stronger interbedded sandstone with pre-existing flaws. The crack propagation process of two-layer weaker and stronger interbedded sandstone specimens is studied using acoustic emission (abbreviated as AE) and digital image correlation (abbreviated as DIC) techniques, with the focus being on the influences of the flaw position. The results indicate that the crack initiation mode and final failure mode of weaker and stronger interbedded sandstone are dominated by the tensile mechanism. Three crack initiation modes are identified, which are closely related to the flaw position. When the flaw exists inside the weaker layer or the flaw is far away from the interface, the crack initiation mode is the tensile anti-wing crack initiation from the flaw tip. Whatever the flaw positions, the upward-propagating cracks arrest within the stronger layer, but the downward-propagating cracks eventually cross the weaker layer, which is the main mechanism causing failure. This study sheds light on the failure mechanism of LCRs considering the flaw position under uniaxial compression. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2024.

Abstract ：
针对贵州紫金部分矿井巷道围岩存在溶洞经常导致地下工程围岩呈现不稳定状态或剧烈破坏现象这一典型工况，利用简化的类岩石试样开展真三轴压缩试验，结合声发射和内窥摄像头监测围岩的变形和次生破坏行为.研究表明：1)溶洞将导致试样z轴峰值荷载降低约25%,次生破坏的出现时间更早，且主导性破坏更加集中地出现在峰值应力时段. 2)位于隧道右上侧的溶洞导致隧道右侧围岩呈现一种新的板状破坏，即破坏由隧道-溶洞的中间岩柱起始、沿隧道右侧壁表层围岩纵向发展、并最终形成岩块向内移动，该类型破坏的起始位置和岩块厚度与典型板裂破坏明显不同. 3)压缩型应力和剪切破坏在隧道围岩的板裂破坏过程中占据主导地位，且由于三维溶洞位于隧道右上方，其对隧道下方和左侧围岩的影响相对较小. 4)球形溶洞导致其与隧道之间的岩体内出现更为密集的次生拉伸和剪切裂纹，即该区域内岩体破坏程度明显高于其他位置.

Abstract ：
基于地下水封洞库工程特征与典型洞库工程实例，整理分析大量洞室围岩内部变形、表层变形、波速与锚杆应力等监测数据.结果表明：预埋的多点位移计测点位移主要为0.5～3.0 mm,收敛位移监测值主要为4～8 mm,拱顶沉降监测值主要为3～6 mm,围岩时效变形不明显；围岩变形与爆破开挖有关，当掌子面或后续台阶开挖面接近监测断面时，变形出现陡增；围岩质量越差，开挖面空间效应越不明显.提出洞室围岩损失位移确定方法，发现损失位移占最终收敛位移50%～60%;基于波速变化率提出围岩松弛程度评价指标，发现围岩最大松弛程度约为0.47,松弛深度为1.5 m;洞室围岩锚杆受力普遍较小，锚杆拉应力与围岩变形基本同步变化.

Abstract ：
为模拟岩体中原生裂隙的真实破坏行为,基于含二维和三维预制裂隙的类岩石试样的单轴压缩试验开展了相应的离散元模拟研究.试验和模拟结果表明:内部次生破坏率先出现在内置二维裂隙下部和三维裂隙周围,且次生拉裂纹与预制裂隙在走向方向上完全平行呈条带状分布.裂隙倾角的增大对岩样的破坏有不同程度的影响,随着裂隙倾角逐渐减小,次生拉裂纹越来越明显,翼裂纹的曲率越来越大,内置三维裂隙附近的拉裂纹簇分布范围越来越大.同时,次生剪裂纹的产生也随着裂隙倾角的减小而发育越来越明显,连通性增强,试样越容易发生破坏,说明随着预制裂隙倾角在一定范围内减小,试样强度呈现递减趋势.
