| As there are some concealed mined-out areas in a certain open-pit mine,safety trouble produces on stream.On the basis of the theory of genetic algorithms,the program of modified genetic algorithms is worked out with MATLAB language in the text,the most unsafe slip surface and safety factor of the slope is searched by the program,and the influence of concealed goaf on stability of the slope is analyzed,and the parameters of the slop are optimized.These are basis of safety in production for the mine. |
