Abstract
The Bureau of Mines has successfully developed and tested a machine for spraying sealant onto coal mine roof and ribs. Dry material is transported pneumatically to a water-adding nozzle designed to provide dust-free spraying while being nonplugging and self- cleaning. The machine is self-cleaning, 35 inches in height, and capable of applying 1/2-inch-thick coatings at over 1,000 ft2/hr.
