Abstract：Through the analysis of relevant literature review and geological data in Qianjiaying Mine, the geological tectonic factors are divided into five parts: buried depth contour, fault number, fault average drop, fault average length and fault density. By means of cluster analysis and analytic hierarchy process, five parts of geological structure factors are simplified, and the weights of geological structure factors at various levels in Qianjiaying Mine are confirmed. According to the statistics of gas outburst index in different levels, combined with the gas dynamic phenomenon of-850m main cross cut area in Qianjiaying Mine, the gas outburst critical value of geological structure in Qianjiaying Mine is 0.308. This method quantifies the geological structural factors, and provides a way to analyze the geological structural factors.
