Abstract: In order to reduce safety accidents in shaft freezing construction of coal mine, taking the coal mine shaft freezing construction project as an example, according to the data of analysis and summary of the implementation of the project, the weights of each evaluation index of construction risk factors is determined by AHP method, and the fuzzy evaluation method is used to establish a comprehensive evaluation matrix of risk factors.According to the principle of maximum membership degree, the high-risk indicators and general risk indicators in the construction of the shaft freezing method are determined.Based on the results, the risk pre-control measures are formulated from the aspects of organization, technology and economy to effectively control the construction risk of the mine shaft freezing method.
