Implication

Reveals the corrosion characteristics and performance degradation of bolts in a high mineralized environment, suggesting improved anti-corrosion measures.

Key Points

The study aims to explore the corrosion behavior and performance degradation of bolts in deep coal mining environments.
Conducted corrosion experiments on ordinary and zinc-infiltrated bolts
Utilized XRD and tensile tests to assess performance degradation
Established a time-varying model for predicting bolt performance degradation
Analyzed correlations between corrosion depth, ion concentration, and strength loss
Bolts in high mineralized environments exhibited pitting corrosion.
Zinc-infiltrated bolts demonstrated significantly better ion erosion resistance than ordinary bolts.
Increased ion concentration led to greater performance degradation in bolts.
Corrosion depth is linearly positively correlated with strength loss.
Cl− concentration and temperature negatively correlate with bolt service life.
