Organization: ASTM International
Publication Date: 10 June 1997
Status: inactive
Page Count: 1
ICS Code (Non-metalliferous minerals): 73.080
scope:

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.
