Study on the Damage Evolution of Weathered Granite under Different Confining Pressure Based on Hoek-Brown Failure Criterion and Acoustic Emission Parameters

Kang Zhao, Qiang Nie, Jun Wu, Yajing Yan et autres

Abstract The stability of the mine construction is significantly impacted by weathered granite (WG), which presents a significant risk to the security of workers and equipment. In order to investigate the strength characteristics of WG under different confining pressures, acoustic emission (AE) …

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 …

Experimental Study on Deformation Behavior and Permeability Evolution of Sandstone Responding to Mining Stress

Yang Liu, Tong Zhang, Jun Wu, Zhengyang Song et autres

Mining-induced hydromechanical behavior of sandstone is critical to mining safety and disaster prevention. To investigate the evolution behavior of the mechanical and permeability properties of sandstone, mining-induced stress was imitated by increasing axial stress and decreasing confining stress, and a set of …

An FPGA Implementation of TCM Cascade Space Time Block Code

Jun Wu, Xiao Bo Wu

Trellis coded (TCM) modulation can obtain the coding gain without increase the transmission power and the bandwidth but it can not obtain diversity gain, and space-time block code (STBC) can provide diversity gain in a simple encoding and decoding way, though its …
