CARBOFILL

CARBOFILL
Phenolic Resin Foam for Cavity Filling, Gas Sealing and Fire Fighting in Mining

CARBOFILL - low-emission - high foaming

CARBOFILL is a fast reacting dual component phenolic resin foam which starts foaming immediately on mixing and exhibits excellent physical properties. This product ensures a significant reduction in roof falls of stone or coal while filling the excavation. Thus CARBOFILL contributes to improving the operational safety and efficiency in mining.

CARBOFILL is well suited for:

· Fire fighting
· Filling excavations in drifts and longwalls
· Cavity filling to prevent gas accumulation
· Injection for rock stabilisation
· Filling dams to prevent air penetration into goaf
· Stabilisation of burst material
· Sealing gas dams

Due to the nature of the CARBOFILL foam only light shuttering is required and in some cases it is not required at all.

CARBOFILL can be applied via hose, pipe or injection bolt. Tubular films, pack bags or Bullflex hoses can be filled with CARBOFILL.

CARBOFILL - extinguishes mine fire

To apply CARBOFILL the A (resin) and B component (hardener) are pumped on site at a ratio of 4:1 via two-component pump and hoses. Once at the injection site the resins are thoroughly mixed via an inline mixer and injected immediately.

The Minova pumps are equipped with a scale to control the processed volume of the product. Improper emissions can be avoided if CARBOFILL is used according to the given permissions.

Two pneumatically driven pumps are available for the on-site application of CARBOFILL:

· SK 90 gear pump for pumping distances of up to approx. 300 m

· PHP piston pump for pumping distances up to approx. 800 m

Benefits of CARBOFILL

· High foaming factor
· Low density
· Reduced shuttering needs
· Easy handling
· High filling capacity, production can be started immediately
· No waiting time after completion of the filling work
· Low-emission
· Extinguishes mine fire
