Abstract

Abstract: To meet the target of Kailin Group to be bigger and stronger, production capacity of Yongshaba mine should reachs 2 million t/a, which could be realized with multiple middle pieces mining together. Filling mining area is needed to control settlement of mining area when 2~5 middle pieces mining together. Through finite element calculation, and stability analysis was done on calculation results, aim of improve extraction security in mining area and realize multiple middle pieces safe mining was reached.

Key words: Yongshaba mine, Stability analysis, Settlement
