| Abstract: | Basic thoughts and approaches of the grey relation analysis(GRA) are firstly introduced in this paper. GRA method is adopted to calculate grey relation grade and magnitude of the dangerous degree of the mined-out stopes, based on main factors of influencing the dangerous degree of the minded-out stopes and their weight. A practical example on the evaluation of risk degree of underground mined-out stopes, which proves the feasibility and effectiveness of GRA, can provide reference and a viable alternative for decision makers' sights of the whole disposal of underground mined-out stopes. |
