Abstract:

The model for mining stope structural parameters optimization may result in“state out of balance” phenomenon when the evaluation indexes tend to the edge state.To slove this problem，the variable weight theory was introduced into the scheme evaluation of mining stope structural parameters.Combined with the ideal point method，9 indexes which influence scheme decision mostly were selected from three angles including economy，technique and safety condition，to build the variable weight and ideal point model.In the model，the variable weight which more coincidence with actual situation of each scheme were calculated by variable weight theory based on the constant weight of each evaluation indexes.Then，the quality distance of all schemes were calculated by ideal point method and the preferential order were given.The model was used in stope structural parameters optimization of a mine and the results reflected the superiority of the model in weight calculation.The optimized result is more suitable for engineering practice.

Key words: stope structural, parameters optimization, mining, variable weight theory, ideal point method, evaluation index, evaluation model
