| Abstract: | Aiming at the mining conditions of the testing nugget in north area of Xiaoguanzhuang Iron Mine,upward drift cemented filling mining method is taken.Optimized cemented filling scheme in lab is applied to the testing nugget,which obtains expected results after industrial testing on-444m level of the first mining layer.Against the unclosed roof and drainage problems with drift filling process,reasonable solving measures are put forward.Finally the filling mining scheme is determined,which has guidance in mining production of Xiaoguanzhuang Iron Mine. |
