Abstract
Conventional flame channeling operates continuously at over 120 db-- flame drill channeling operates at a maximum of 95 db. The latter process was developed under this program. Individual drill holes are spaced to leave narrow rock webs. Sound and dust passing from the holes are effectively treated by a muffler and water injection.
