Abstract

See full text

A mine safety dust exhibiting improved dispersion in water. The rock dust includes dolomitic limestone particles which, when mixed at the mine site to form a slurry, stay in suspension during intermittent operation of spray machinery and with a reduced need for continuous mixing. The rock dust composition includes an inorganic salt that acts as a dispersant to improve dispersion of the rock dust in water and further acts as a deflocculant to keep the dust particles in suspension in the resultant slurry.
