Abstract
A high-expansion foam system was developed and tested on a continuous mining machine under actual operating conditions to determine whether respirable coal dust emanating from the mining machine could be suppressed more effectively by the foam than by the water sprays conventionally used. The utility of the system was demonstrated. Test results tend to show that foam application is more effective than water sprays in suppressing respirable coal dust. Sufficient statistical data were obtained to indicate that foam is more efficient than water in suppressing total float coal dust.
