A laboratory study is made for developing a water/surfactant/polymer-augmented high-expansion foam capable of suppressing coal dust. The rationale for use of the foam is based on the high expansion factor of foam. Foam solutions containing a surfactant and a water-soluble polymer capable of trapping 90-95% of the airborne dust generated in laboratory coal cutting experiments are developed as are methods for generating coal dust and miniature high-expansion foam generators.
