Overview

Experiments demonstrate that corrosion behavior reduces mechanical properties in bolts, indicating further fracture risks when protecting roadway support materials.

Key Points

  • Fracture risk arises as corrosion behavior degrades mechanical properties and effectiveness of bolts.
  • Long-term corrosion tests reveal a decrease in yield strength of bolts by 11.8% due to environmental conditions.
  • Assessment using corrosion tests highlights the effects of high temperature, humidity, and stress on bolts' failure mechanism.
  • Findings indicate the need for improved corrosion protection to enhance stability of roadway support materials in deep mines.
