This innovative technique effectively cleans surfaces, prepares them for coating or welding, removes rust, and strips paint, all while minimizing damage to the material, ensuring an environmentally-friendly and cost-effective solution for diverse
Effect of Stress Anisotropy on the Efficiency of Large-Scale Destress
2020927 Large-scale panel destressing is a rockburst control technique that is used to create a stress shadow in the ore pillar to be mined. The technique aims to reduce the pillar burst proneness by deviating the major induced principal stresses away from the concerned zone of interest. The destress panels, situated in the pillar hanging wall, are
