Tackling one of underground mining’s long-standing challenges: how to achieve continuous, large-scale extraction of thick metal ores without leaving inter-level rock pillars.

At BGRIMM, we’ve developed a Safe Multi-Level Panelized Continuous Mining Method that replaces traditional rock pillars with engineered backfill isolation layers. This innovation enables vertical continuous mining in thick, stable orebodies—without sacrificing safety or efficiency.

Key Advantages:

No inter-level rock pillars – resource recovery rate exceeds 90%

Eliminates backfill contact issues in two-step subsequent backfill stopes

Enables large-scale continuous mining with better production sequencing

Daily output per stope ≥ 1,000 tonnes, with dilution and loss rates each under 8%

Already deployed across multiple major mines—delivering stronger safety performance and significantly higher resource recovery. Ideal for thick, stable metallic deposits where traditional pillar-retaining methods limit efficiency and resource utilization.
