The coal mine environment is easy to cause corrosion damage to the anchorage material in long-term use because its complexity, which threatens the safety of roadway support. To characterize the corrosion characteristics of coal mine environment, the corrosion factors and corrosion tendency of coal mine environment were studied. The environmental characteristics and main corrosion factors of coal mine were analyzed based on field investigation. The multi-parameter coupling evaluation method of coal mine environmental corrosion tendency is designed by analytic hierarchy process-entropy combination weighting and membership degree analysis. The environmental corrosion tendency grade of underground roadway in Gaojiabao Coal Mine was determined by industrial application test. The results indicate that the coal mine environment can be divided into three categories: water environment, atmospheric environment and surrounding rock environment, including 9 main environmental corrosion factors. By index weighting analysis, the weight of water environment was determined as
