Comprehensive Research on the Technology of Residual Ore Column Recovery Under Dry Loose Overburden Rock Filling
In order to ensure the safe recovery of the residual ore column under the dry loose covered rock filling,the advanced grouting technology is used to consolidate the filling body to form an artificial false roof with a certain strength,and the appropriate mining method is optimized through the comparison of the recovery process and technical safety economic indicators,which ensures the safety of the top plate of the operation.Results of on-site industrial tests prove that the use of advanced grouting consolidation technology can well maintain the safety of the top plate of the stope,and can provide reference for the recovery of similar mine residual ore columns,which is of good engineering practical significance.
