Figure 1 Upward approach filling mining method
1-Pedestrian ventilation patio; 2-Ore chute; 3-Layer roadway; 4-stage transport lane;
5-filled patio; 6-recovery approach; 7-filled stratification
A pedestrian ventilation patio is arranged at each end of the stope, and a mine drainage well is arranged in the center. The pedestrian patio is detached from the bottom up with the stratified approach, and is gradually replaced by a stepped patio constructed in the filling. The pedestrian ventilated patio in the upper unexamined section can also serve as a filling well.
The ore-boring well can also be erected in the post-harvest filling body, or placed in the lower rock, and connected to it by segmented roadway or sectioned roadway.
The layered roadway is arranged perpendicular to the direction of the approach.
The alignment of the upward approach filling mining method is shown in Figure 1.
