Selection of Mining Methods for Deep Thick Large Ore Based on AHP-TOPSIS Evaluation Model

Abstract

Abstract: In view of the requirements for the improvement of production capacity and production effi⁃ ciency in the mining of deep steeply inclined thick orebody in Gaofeng Mine，the optimization of mining scheme was studied. Firstly，a comprehensive evaluation model based on AHP and TOPSIS is established， and three mining schemes are selected according to the technical conditions of orebody mining. Using AHP-TOPSIS model，11 indexes were selected from three aspects of technology，economy and safety for comprehensive evaluation，and the optimal mining method was segmented open stope subsequent filling mining method.

Key words: mining method, thick ore body, AHP-TOPSIS comprehensive evaluation
