Abstract ：
CFD simulation tests were carried out to study the asymmetric flow phenomenon caused by the combination effect of tunnel slope and longitudinal fire location in a naturally ventilated tunnel. The result shows that the tunnel slope and the longitudinal fire location can both create the induced longitudinal flow solely. The longitudinal flow within tunnel induced by the stack effect caused by the tunnel slope is normally unidirectional, flowing uphill and the speed increases gradually with the tunnel slope. While the longitudinal flow induced by the thermal pressure difference caused by the uneven distribution of upstream and downstream smoke transportation can be bidirectional, which depends on the longitudinal fire location (also known as the downstream and upstream tunnel length difference, Delta L = L-down - L-up). Therefore, the induced longitudinal flow under the combination effect of tunnel slope and longitudinal fire location is very complex. For tunnels going uphill from left (upstream) to the right (downstream) portals, the two effects are positively added when the fire is located at the upstream tunnel (Delta L > 0), while the two effects are counteracted when the fire is located at the downstream (Delta L < 0). To quantify the strength of asymmetric flow caused by the two effects, an empirical equation of mass flow rate of induced longitudinal flow is proposed. Meanwhile, a model to predict the smoke back-layering length under the two effects is also proposed and validated by former experimental data. A prediction model on the upper critical fire position where the two effects are completely canceled out is proposed. Another critical position (the lower critical fire position) where the smoke flow can achieve unidirectional transportation in an inclined tunnel under natural ventilation conditions is deduced as well.

Abstract ：
为探讨复合矿物的微波加热机制，使用COMSOL Multiphyics软件，基于任意拉格朗日-欧拉(ALE)方法建立起环绕式微波加热模型来开展对不同组分结构和占比的复合矿物模型的温升特性研究.研究结果表明：相比于无搅拌加热模型，在铜片长度为5 cm,转速为(π/3) rad/s的环绕式模型中，矿物加热的效率更高，温度分布更均匀；复合矿物组分结构的变化会改变电磁波的分布，黄铁矿包裹方解石模型的微波加热效率低于方解石包裹黄铁矿模型；在黄铁矿包裹方解石模型中，黄铁矿厚度变化会引起电磁波相位变化，使得矿内电场热点和冷点偏移，并且其厚度大小在穿透深度前后对比，射入的电磁波强度差距较大，电场强度有显著差异；相同组分占比下，非均质矿物整体的电场模比复合均质矿物更低更稳定，组分间的电场强度更为接近；随着黄铁矿占比的增加，非均质矿物整体在微波加热30 s后的温度变化可分为小波峰区(0～10%)、大波峰区(10%～50%)、平稳区(50%～75%),组分间的温差逐渐变小.

Abstract ：
To investigate the microwave heating mechanism of composite minerals, a circumferential stirring model based on the Arbitrary Lagrangian-Eulerian (ALE) method was established by COMSOL Multiphysics software. This model aims to study the temperature rise characteristics of mineral models with different component structures and proportions. The results show that the heating efficiency and uniformity of the mineral are higher in the stirred heating model with a 5 cm copper disc rotating at (π/3) rad/s compared to the non-stirred heating model; The different component structures of the composite mineral result in different electromagnetic wave distributions, which induces the microwave heating efficiency of the py-rite-enclosed calcite model is lower than the calcite-enclosed pyrite model; In the calcite-en-closed pyrite model, the variation of pyrite thickness changes the phase of electromagnetic wave, leading to the displacement of hot and cold spots in the mineral. Furthermore, when comparing the pyrite thicker and thinner than the penetration depth, there is a significant disparity in the incident electromagnetic wave intensity, resulting in noticeable differences in electric field strength; At the same component proportion, the overall electric field of heterogeneous minerals is lower and more stable, and the electric field intensity between components is closer than in composite homogeneous minerals; With the proportion of pyrite increases, the temperature variation of heterogeneous minerals after 30 s microwave heating can be divided into three regions: small peak region (0-10%), large peak region (10% - 50%), and stable region (50% - 75%), and the temperature differences between components gradually decrease. © 2024 China University of Mining and Technology.

Abstract ：
In this work, the characteristics of the exothermic reaction between ammonium nitrate and sulfide ores were explored using COMSOL Multiphysics. This reaction can cause an increase in temperature within the blast holes of sulfide mines and can potentially induce premature explosions of the explosives. Initially, simulations were conducted to observe temperature variations in blast holes before and after the loading of explosives. Then, the impact of blast hole diameter and initial temperature on the thermal environment was assessed. Subsequent analysis focused on the fluid field's dynamics, examining flow rate changes and the concentration of signature gases produced by the reaction. Additionally, the influence of blast hole diameter on these parameters was evaluated. The results show that the blast hole temperature is positively related to its diameter and initial temperature. When the diameter of the blast hole is 120 mm and 165 mm, a significant change in flow rate is observed, with a trend of being rapidly increased and then rapidly decreased. The production of NH3 is always found to be greater than that of the other two gases. As for NO and SO2, their production is characterized by an approximate ratio of 1:2. The numerical simulation results can provide important theoretical guidance for the spontaneous detonation of blast hole in sulfide mines.
