Efficient and Stable Gas Drainage Technology for the Entire Life Cycle of Boreholes in Soft Coal Seams

Bo Li, Jian Yang, Junqi Cui, Peng Lu et autres

Gas drainage technology is a crucial method for preventing and controlling coal and gas outburst. To address the susceptibility to deformation of extraction pipes in soft coal seams, three types of internal support extraction pipes (ISEPs) were developed: the horizontal internal support …

VGGT-Long: Chunk it, Loop it, Align it -- Pushing VGGT's Limits on Kilometer-scale Long RGB Sequences

Kai Deng, Zexin Ti, Jiawei Xu, Jian Yang et autres

Foundation models for 3D vision have recently demonstrated remarkable capabilities in 3D perception. However, extending these models to large-scale RGB stream 3D reconstruction remains challenging due to memory limitations. In this work, we propose VGGT-Long, a simple yet effective system that pushes …

Axial crashworthiness of vertex-based hierarchical non-convex tube

Jian Yang, Bin Dai, Yong Tao, Jun Shi

Inspired by the traditional non-convex tube and the cross-sectional microstructure of bamboo, a vertex-based hierarchical non-convex dodecagonal multicellular tube (HNCDM) is constructed, and its crashworthiness is studied through a combination of quasi-static compression test, numerical simulation, and theoretical analysis. Firstly, the crashworthiness …

Analysis of energy dissipation characteristics and numerical simulation of surrounding rock control for backfill combinations with different ash/sand ratios

Kang Zhao, Qizheng Huang, Jun Wu, Yajing Yan et autres

To reduce the economic cost of backfilling a mine, layers of cemented materials with different ash sand ratios are often used to backfill the void. In this study, we explored the damage evolution mechanism from the energy consumption point of view for …
