| Abstract: | The Maluping mine of Kailin Group takes the sublevel field subsequent filling method to mine ore, and it can ensure the security of the mining area during the construction and operation. Maluping mine employ supporting anchoring in the central part of the stope roof. The displacement and deformation characteristics of supporting the stope before and after、 the maximum principal stress distribution and the distribution characteristics of plastic zone were analyzed and the analysis of the stability of stope were carried out, then we demonstrate the scientific support patterns. |
