Abstract: Abstract The surface uneven subsidence is one of the important reasons that cause the buildings damaged. The numerical simulation method can be used to simulate the destruction state of the structures and forecast the developing trend of the damage. The return air shaft duct of Niuxi Coal Mine is built on the backfill land and it is seriously damaged. Mohr-Coulomb Model of the return air duct is established to simulate the subsidence and forecast the trends of subsidence and damage. The grouting holes’ reinforcement has good use on the control of the subsidence trends in short terms, but the damage for the subsidence has been solved. So it is suggested that the company should contact some research institutes and engineering companies as soon as possible.
