Historical Standard: ASTM C737-02 Standard Specification for Limestone for Dusting of Coal Mines
SUPERSEDED (see Active link, below)
ASTM C737
1. Scope
1.1 This specification covers limestone suitable for use as dust in coal mines to prevent coal dust explosions.
Note 1In 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.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
