Standard Specification for Limestone for Dusting of Coal Mines
Most recent standard

Summary

1.1 This specification covers limestone suitable for use as dust in coal mines to prevent coal dust explosions.

Note-In coal mine operations, limestone is dusted onto coal exposures in sufficient amount so that not less than 65% of all loose dust shall be limestone. With such a concentration of limestone, explosions cannot initiate or be propagated from nearby gas explosions. The limestone must be substantially dry in order to dust satisfactorily.
