The unique environmental conditions of high-altitude mining areas — including low temperatures, strong radiation, and large temperature fluctuations — tend to cause concrete to experience freeze–thaw damage, accelerated carbonation, and crack development, which seriously affect the safety and service life of engineering structures. This paper starts from the core causes of concrete durability degradation in high-altitude mining areas and, based on the material characteristics of concrete and the practical needs of mining engineering, systematically explores enhancement paths such as material optimization, construction control, protective reinforcement, and monitoring and early warning. The aim is to provide theoretical reference and practical guidance for addressing the issue of insufficient concrete durability in high-altitude mining areas, thereby ensuring the long-term stable operation of mining infrastructure.
