| Abstract: |
| Multi-point discharging is an effective method for improvement of the tight-filling of drift-and-fill mining while the use of a detonating cord to cut-off a plastic filling-tube is a new way to change the discharging-point location during filling so as to realize the multi-point discharging.The conception,test and application effect of this new method are outlined in this paper. |
