Abstract
Due to the excessive coal mining in Sandaobian area of Chengde city,a large number of goafs and potential safety hazards appear.In order to reduce the economic loss,the mined-out research areas of No.Ⅱand No.Ⅲ coal seams in the main mining area of the Sandaobian area are selected,and the stability of the mined-out areas is evaluated comprehensively.On the basis of particular case of the environmental condition and mining activity,the factors such as the characteristics of overburden, coal deposit and mining technology,etc.are selected as the main parameters affecting the stability of the goaf,and the fuzzy matrix is established by the fuzzy mathematics method.The evaluation factor weight is qualified according to the classification of evaluation factors.A comprehensive evaluation is conducted to obtain unstable and understable regions,which are also veri-fied by some areas such as drilling and ground investigations.The result shows that using the fuzzy matrix established by fuzzy mathematics to evaluate stability of the goaf is in agreement with the reality.The research results provide reliable basis for following grouting treatment,monitoring,etc.,and also provide reference for the similar stability assessment of goaf.关键词
