| Abstract: | According to attribute mathematical theory,attribute recognition model for assessing the stability of goaf foundation was proposed in this paper.Seven parameters including the end-mining time of coalface,subsidence tendency,depth/thickness ratio,complexity of geologic structure,strength of overlying strata,relative position,and activation factor were selected as the indexes and the goaf foundation stability conditions were divided into four grades.Attribute measurement diagrams were rigorously constructed to compute attribute measurement of single index were synthetic attribute measurement,the stability classification of goal foundation samples are recognized by the confidence criterion.An exemplification study showed that the synthetic assessment results agree well with the practical. |
