Abstract
For deep mining of a gold mine in the Altay city, Xinjinag autonomy region, China, it is necessary to evaluate the stability of mined-out areas of upper levels and then to treat those mined-out areas. Based on the features of underground mining, in this paper, a complex system model of stability assessment of underground mined-out area has been set up, which is constituted by 3 sub-systems of geological factors, mining engineering factors and management factors, and this system could be studied and analyzed by using the fuzzy analytic hierarchy process method and the catastrophe theory modeling method. By using those two methods and utilizing measured data of the gold mine, some useful conclusions of stability assessment of mined-out areas have been given out, which would be helpful for the mined-out areas treatment and also for the safely deep mining of the mine.
