| Abstract: | By adopting similar simulation experiment, using collapse column slope in Anjialing Open-pit Mine as research object,this paper discusses the internal stress distribution and change rules under different mining schemes, examines the rationality of the design plan according to the experimental results. The result indicates that "avoiding the collapse column scheme"is the best crossing collapse column scheme for Anjialing Open-pit Mine working face. |
