Incombustible Matter Testing
Verify rock dust application meets 80% incombustible standard per 30 CFR 75.403.
- Have dust samples been collected and tested by MSHA-approved method showing 80%+ incombustible matter content?
- Were samples collected at approved locations including last open crosscut and throughout active workings?
- In areas within 40 feet of methane liberation, does incombustible matter reach 65% or higher as required?
- Is sampling frequency meeting at least bimonthly requirements in gassy mines?
- Are dust sample test records maintained per 30 CFR 75.403-2 with laboratory results on file?
Rock Dust Application and Coverage
Verify application coverage per 30 CFR 75.401.
- Has rock dust been applied to all surfaces including roof, ribs, and floor in treated areas?
- Is rock dust coating uniform with no bare or heavily coaled spots that would indicate inadequate coverage?
- Is rock dusting extended beyond coal cleanup operations and not just in most recently worked areas?
- Are travel roads and belt haulageways rock dusted including under belt structure per requirements?
- Has fresh rock dust been applied to cover new coal accumulations since previous application?
Rock Dust Product Quality
Verify rock dust product specifications.
- Is rock dust product from MSHA-approved source with certification of calcium/magnesium carbonate content?
- Is rock dust dry and free-flowing (not caked) to ensure proper dispersion when disturbed by blast wave?
- Does rock dust meet fineness requirement of at least 70% passing through 200-mesh screen?
- Is rock dust stored in dry location protected from moisture that causes caking and reduced effectiveness?
Automatic Rock Dust and Water Barrier Systems
Inspect supplemental explosion suppression systems.
- Are stone dust barriers or water trough barriers installed at required locations per mine explosion suppression plan?
- Are barriers loaded with correct quantity of dust or water per manufacturer design specifications?
- Are barriers inspected at minimum weekly to ensure integrity and proper loading?
- Are automatic triggered barrier systems (if used) tested and functional?
