Based on the correspondence analysis model and the method of mining the cause and time of construction accidents. Using Python crawler technology to crawl 3896 data of the causes of construction safety accidents in China Construction Safety Supervision Information System from 2012 to 2018, a contingency table of various types and times of accidents in construction safety accidents was established. By using factor analysis, the relationship between Q-factor analysis and R-factor analysis in the corresponding factor analysis model was established. The model was analyzed and optimized by a special point removal method, and the convergence of the model was strengthened. Finally, the causes of construction safety accidents in the model and the time of one day and one year were calculated and drawn in the corresponding analysis chart of the two-dimensional model. Mining the relationship between them according to their relationship in the graph based on the data collection of 3896 building safety line accidents, this paper put forward the method of mining the main causes of accidents, and used SPSS platform technology to mine the accident data. The results showed that the occurrence of electric shock and drowning was closely related to August, fire and explosion were closely related to February, and poisoning and asphyxiation were closely related to January. 5-6 a.m. was closely related to fire and explosion, and vehicle injury was closely related to 8-9 p.m. To put forward prevention suggestions for construction accident prevention.
