Abstract

See full text

Rock dust is applied to a coal mine wall for mine fire suppression in combination with a chemical foam containing a saturated fatty acid, preferably stearic acid, which imparts hydrophobic properties to the rock dust particles, avoiding agglomeration. The rock dust and foam containing a saturated fatty acid are combined by causing the rock dust and foam to flow through separate conduits to a combiner from which the resulting mixture is caused to flow through a nozzle for application to the mine wall.
