    Design of backfilled retaining wall in an mine in Inner Mongolia

    • By analyzing the treatment scheme of goaf, and according to the large width and height of the partition wall required in mine, the force of filling retaining wall was analysed and calculated, and a new flexible wall was proposed.Comparing with other filling blocking wall, the new wall could reduce the filling cost and determine the retaining wall's permeability but strength requirement still satisfied.The production cycle of the flexible wall is short, reducing cycle time of mining and backfilling and providing a reliable guarantee for safe mining of the point pillar.It is concluded that those technical measures and practice can be taken as reference for other mines of similar conditions.
