含隐伏空区的露天矿边坡稳定性及参数优化研究

某露天矿在设计的露天采场境界内存在一定数量的隐伏空区,将给露天矿的生产带来较大的安全隐患。为此本文根据遗传算法理论,采用MATLAB语言编制了改进遗传算法的计算程序,对任意形状的边坡滑动面进行搜索,找出其最危险滑面和安全系数,分析隐伏空区对边坡稳定性的影响,并对边坡参数进行优化,为矿山的安全生产提供依据。

STUDY ON STABILITY AND PARAMETER OPTIMIZATION OF ROCK SLOPE IN OPEN-PIT MINES OF CONCEALED MINED-OUT AREAS

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.
