Abstract:

To solve the problem of the difficulty using numerical analysis method to obtain the optimal stope structure parameters of the weight，we propose a technique for order preference by similarity to ideal solution（TOPSIS） based on combination of empowerment comprehensive evaluation method.Considering influence of stope structure parameters of the three categories of factors，such as economy，technology and safety.We establish the evaluation system of a stope structure parameters by the principle of analytic hierarchy process，determine  combination and weights of each indicator using the entropy weight method and analytic hierarchy process （AHP），and calculate the superior degrees of schemes based on the comprehensive evaluation index，finally，realizing，optimization of stope structure parameters.Taking the example of a mine in Hunan Province，nine schemes，fitting an orthogonal model，were tested，five of the nine schemes were assessed by empowerment combination TOPSIS evaluation model.The synthetic superior degrees of schemes are 40.8%，70.2%，26.8%，52.9% and 4.7% for the second，third，fifth，sixth and eighth ones，respectively，and the third scheme becomes the best.
