To conduct scientific and rational evaluation upon mining methods for the exploiting of roof and bottom pillars in Sanshandao gold mine， factors influenced mining methods such as technology economy and safety were considered to establish a comprehensive evaluation index system.Analytic hierarchy process and entropy weight method were used in weight determing of evaluation index， then mining methods can be evaluated through empowerment combination and ideal point method.And the best scheme was obtained after calculating the approach degree of every mining method.Take Xinli mine field of Sanshandao gold mine for example，three schemes were designed for comprehensive evaluation，the relative closeness of the three schemes were 0.37，0.12 and 0.50，respectively.Hence，the third scheme was determined as the best scheme for the exploiting of roof and bottom pillars in Sanshandao gold mine.The result shows that the exploiting scheme choice based on empowerment combination and ideal point method is reasonable and reliable，and has important engineering significance to guide the exploiting of roof and bottom pillars.
