In order to solve the problems of tailings storage and concentration device selection，a comprehensive evaluation standard system based on variable weight analysis method and TOPSIS is put forward to select a preferred solution of three schemes.Firstly，set up a comprehensive evaluation index system，taking cost，operating cost，site conditions，backfill materials properties，put-sand concentration，volume effective utilization rate，maintenance ease of cleaning and working efficiency into consideration.Because of the conventional methods such as analytic weights process may lead to the phenomenon of “imbalances” when evaluating the candidate solutions，through adjust the weight of each factor in the hope of the balance of various factors on the basis of variable weight theory.Secondly，sort of close to ideal solution method through TOPSIS method to obtain superiority degree from different candidates.Finally，a concentration equipment selection in an iron mine in Hebei Province was taking as an example，put forward three proposals which are horizontal sand bin，vertical sand bin and deep cone thickener respectively.Through calculation，the superiority degree of each scheme were 57.5%，72.1% and 88.5%，respectively，deep cone thickener is selected and the result is consistent with the engineering practice.It shows that the comprehensive evaluation index for the choice of backfilling concentration equipment has reference value，and it provides a scientific and reliable analysis method on the optimization problems in engineering practice.
