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 w...
