Abstract

This specification covers limestone suitable for use as dust in coal mines to prevent coal dust explosions. The limestone shall conform to the chemical composition requirements prescribed. The chemical analysis and the particle size analysis of the limestone shall be conducted.

Scope

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

Note 1—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.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
