Stability Analysis and Disposal of Huogeqi Copper Mine Gob in Inner Mongolia

The general status of Huogeqi Copper Mine in Inner Mongolia was introduced in detail including the environment, geographical condition, and character and stability of the gob area. The stability of the gob area was analyzed and calculated based on Coulomb Law and the boundary element numerical simulation method. By comparison, the safety coefficient calculated by theoretical analysis is agreeable with that by numerical simulation. According to the result, combined with engineering practice, the stability of the gob area was analyzed and the corresponding disposal method was proposed. The successful application to the gob area at Huogeqi Copper Mine shows that this method is both convenient and economic.
