Example Embodiment
[0028] The construction scheme of the stope approach arrangement method that is beneficial to filling proposed by the present invention is as follows:
[0029] (1) Stope cutting
[0030] From the middle section ramp 1 to the bottom wall of the ore body, construct a downward ramp connection road 2. After reaching the design layering height of the stope, construct a vein external connection road along the direction of the ore body at the boundary of the ore body 5-8 meters. 3. Then construct a central cutting lane 5 perpendicular to the direction of the ore body every 16-20 meters along the direction of the ore body to the boundary of the upper wall of the ore body, and pass through the pit 4 and the upper wall of the ore body. The return air fills the well 7. Among them, Shunlulu mine shaft 4 runs through the stope and the exiting roadway at the bottom of the stope, and the return air filling shaft 7 runs through the stope and the upper return air filling roadway.
[0031] (2) Stopi...
