Camp Nelson limestone mined in central Kentucky is also used for agricultural limestone, fertilizer filler, and rock dust for explosion abatement in coal mines. Western Kentucky
Spraying it onto coal surfaces in a mine increases the amount of light and cuts down on coal dust. Limestone''s 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.

Milled limestone, referred to as "rock dust" by the coal industry, is an additive used for safety in underground bituminous coal mines. The particles of the milled limestone mix with coal dust to prevent a potential explosion. Rock dust is blown or sprayed (as a slurry) onto the roof, ribs and floor of the mine, and needs to be reapplied on a regular basis to maintain its effectiveness.
