Block Open Stope Succedent Filling

Block Open Stope Succedent Filling

Deep-hole drill jumbo is adopted to construct downward parallel deep holes in the drilling chamber. After side caving, ore is discharged by scraper into orepass. Ore block has two-stage stoping. After the first-stage stoping, mined-out areas are filled with cemented filling materials to form stable support. Then the second-stage stoping is carried out.

TECHNOLOGY CHARACTERISTIC

Stable, sharply inclined, thick and extremely thick orebodies; extremely thick inclined, slightly inclined and horizontal orebodies.

Large production capacity, centralized management, low mining costs, and high degree of safety.

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.
