Mine Shaft Sealing: Airtight Ventilation Stoppings & Rock Stabilization

Underground mining operations rely on precise atmospheric ventilation to supply fresh air to working faces and expel noxious gases. Poorly sealed ventilation stoppings, bulkheads, overcasts, and shaft collars allow valuable air to short-circuit, drastically increasing ventilation fan power costs while reducing worker safety. Tiger Foam™ closed-cell polyurethane foam provides an on-demand, rapid solution for underground crews to build airtight ventilation barriers, seal perimeter air leaks against irregular blasted rock, and consolidate fractured strata.

Key Application Benefits

  • Airtight Ventilation Stoppings: Expands into irregular jagged rock crevices and around bulkhead timbers/steel stopping frames, eliminating ventilation air bypass instantly.
  • Portable, Self-Contained Application: Compact pressurized cylinder kits require no heavy compressors, electrical generators, or hydraulic pumps—easily transported deep into headings and confined shafts.
  • Rapid 30-Second Cure: Foam expands and sets tack-free in 30–45 seconds, allowing ventilation crews to achieve airtight seals and rebalance air currents without shaft downtime.
  • Class 1 Flame & Smoke Safety: ASTM E-84 Class 1 (A) formulation ensures low flame spread and minimal smoke development in critical underground confined spaces.
