| Abstract: |
| The mining method which will be used at Hebei Fanshan Phosphorus Mine is a new one combining the sublevel caving mining method with sill pillar and sublevel caving mining method without sill pillar.The selection of structure parameters of the stope will directly affect the elaboration of the advantages of this method. Based on physical modelling drawing test and computer simulation drawing test,it is proved that the parameters selected are feasible and reasonable,so as to lay a foundation for using the mining method at Hebei Fanshan Phosphorus Mine. |
