Sublevel Room and Pillar Stoping

Sublevel Room and Pillar Stoping

Vertically, there are 3-4 sublevels in the stope room, with each measuring 12-15m in height. At each sublevel, medium- and deep-hole drill is adopted to construct upward fan-shaped holes, and charging jumbo to put explosives into the holes. Caved ore is discharged by scraper into orepass.

TECHNOLOGY CHARACTERISTIC

Stable, sharply inclined orebodies with thickness above the moderate level.

Stoping at several working faces, centralized management, high stoping capacity, mechanization, high degree of safety, and good ventilation.

MODE OF TRANSPORT

There are many transport methods, such as rail transport, trackless transport and belt conveyor. The specific method should be determined based on the orebody development scheme, transport volume and distance, mineral composition, ore properties, mining method and techno-economic comparison results.
