| Abstract: |
| The characteristics,mechanism and rule of macroscopic destroy and the deformation prediction method for surface movement with mining steep veins by caving method is different from that of colliery.The former belongs to the tectonic-stress typical opening unstressing while the latter belongs to the gravity-stress typical opening unstressing.In this paper,the characteristics,the mechanism and rule of macroscopic destroy are briefly discussed and new method used for the prediction of deformation for this kind of veins is presented.The method has been successfully used for the exploitation design in a certain mine.The method and its principle can be used in steep metal veins,which are mined by caving method and have remarkable horizontal tectonic stress.It has become a new sort of surface movement prediction different from that of colliery. |
