适用范围: 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.
