Explosion, mine operators routinely cover the ? oor, rib and roof areas of mine entries with a generous applica- tion of inert rock dust. Pulverized limestone rock dust is commonly used. The percentage of rock dust is frequently checked by mine inspectors. Federal law requires that all areas of a coal mine that.

Spraying it onto coal surfaces in a mine increases the amount of light and cuts down on coal dust. Limestones sturdiness makes it hold up through the cycling between freezing and thawing, as well as to other forms of abrasion. Limestone is easier to mine and causes less damage to mining equipment and transport vehicles than harder silicates.
