Use of rock dust and water under the Federal Mine Safety Code in limiting coal-dust explosions

Technical Report ·
OSTI ID:7220497
Widespread explosions in coal mines can be prevented if rock dust of suitable size and composition is applied effectively within two or three cuts of face; distance between end of rock dusting and face should never exceed 80 feet. Water should be used on cutter bar of mining machines, and coal piles should not only be wetted after blasting but kept wet during loading.
