HUNAG Shen;ZHOU Ping;HUANG Maojun;Zijin Mining College,Fuzhou University;Fujian Makeng Mining Co.,Ltd.;  
In view of the complexity and uncertainty of the collapse of goaf,seventeen main factors that affect the stability of goaf are determined and the weight of each factor is determined.The second-level fuzzy comprehensive evaluation model is established and applied to the stability of goaf Sexual Quantitative Analysis.The results show that the second-level fuzzy comprehensive evaluation model established by the fuzzy mathematics theory can more accurately reflect the degree of stability of goaf,which is in line with the actual situation and provides a feasible evaluation for the stability degree of underground mined-out area ideas and methods.
