Exploration of durability enhancement paths for concrete in high-altitude mining areas
高海拔矿区混凝土耐久性提升路径探析

摘要

高海拔矿区特殊的低温、强辐射、大温差环境，易导致混凝土出现冻融破坏、碳化加速、裂缝发育等问题，严重影响矿区工程结构的安全性与使用寿命。本文从高海拔矿区混凝土耐久性衰减的核心诱因入手，结合混凝土材料特性与矿区工程实际需求，系统探析材料优化、施工管控、防护加固及监测预警等提升路径，旨在为解决高海拔矿区混凝土耐久性不足问题提供理论参考与实践方向，保障矿区基础设施长期稳定运行。

Abstract

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.
