闭坑高瓦斯矿井中煤岩体在水和瓦斯的劣化作用下力学特性劣化,这将直接影响其稳定性和安全性。为研究水-瓦斯耦合作用下煤岩抗压特性,基于水-岩-气耦合试验系统,开展了浸泡环境下的全水浸(EW)、半水浸半气浸(WG)及全气浸(EG)煤样和干燥(CZ)煤样的单轴压缩试验,分析了煤样抗压强度及变形破坏特征,并从煤样浸泡前后的组分、宏观结构及破裂断口细观特征的角度,揭示了水-瓦斯耦合作用下煤岩的宏观、细观劣化机制。结果表明,在三种浸泡条件下,煤样抗压强度较干燥煤样均降低,EG组、WG组和EW组煤样抗压强度分别降低了18.92%、38.31%和53.45%,三种浸泡条件下煤样破坏模式由干燥煤样的剪切破坏转变为剪切-拉伸混合式破坏,破坏程度也随之增大,煤样由脆性破坏转变为塑性破坏,导致浸泡后煤样局部化带范围和错动程度增大;煤样在三种浸泡环境中劣化效果主要表现为:1)水和瓦斯的侵入导致煤样内部黏土矿物分解和析出,与CZ组相比,EG组、WG组和EW组煤样平均黏土矿物含量分别降低了3.8%、28.85%和45.94%,煤样孔隙结构发生改变;2)各组煤样浸泡后表面出现劣化效应,EG组表面孔隙发育程度劣于EW组,且EW组煤样表面出现剥落现象,WG组煤样水浸部分孔隙发育程度要胜于气浸部分;3)水和瓦斯的劣化作用使煤样内部孔隙结构发生改变,EW组、WG组和EG组煤样破裂断口平均孔隙率较CZ组分别增加了706.84%、362.95%、147.47%。在三种浸泡环境下煤样初始承载结构被破坏,降低了煤样破坏前储存能量的能力,破坏后煤样内部的剩余弹性能降低,耗散能增加,声发射累计振铃计数降低。上述研究对于认识闭坑高瓦斯矿井中煤岩体的稳定性具有一定的参考意义。

Avatars, as promising digital representations and service assistants of users in Metaverses, can enable drivers and passengers to immerse themselves in 3D virtual services and spaces of UAV-assisted vehicular Metaverses. However, avatar tasks include a multitude of human-to-avatar and avatar-to-avatar interactive applications, e.g., augmented reality navigation,which consumes intensive computing resources. It is inefficient and impractical for vehicles to process avatar tasks locally. Fortunately, migrating avatar tasks to the nearest roadside units(RSU)or unmanned aerial vehicles(UAV) for execution is a promising solution to decrease computation overhead and reduce task processing latency, while the high mobility of vehicles brings challenges for vehicles to independently perform avatar migration decisions depending on current and future vehicle status. To address these challenges, in this paper, we propose a novel avatar task migration system based on multi-agent deep reinforcement learning(MADRL) to execute immersive vehicular avatar tasks dynamically. Specifically, we first formulate the problem of avatar task migration from vehicles to RSUs/UAVs as a partially observable Markov decision process that can be solved by MADRL algorithms. We then design the multi-agent proximal policy optimization(MAPPO) approach as the MADRL algorithm for the avatar task migration problem. To overcome slow convergence resulting from the curse of dimensionality and non-stationary issues caused by shared parameters in MAPPO, we further propose a transformer-based MAPPO approach via sequential decision-making models for the efficient representation of relationships among agents. Finally, to motivate terrestrial or non-terrestrial edge servers(e.g., RSUs or UAVs) to share computation resources and ensure traceability of the sharing records, we apply smart contracts and blockchain technologies to achieve secure sharing management. Numerical results demonstrate that the proposed approach
