Abstract
A continuous channeling method was designed that reduces operating sound levels in drill channeling machines to 100 db. This new method relies on a small-diameter, oxygen-enriched burner to produce narrow channels. Sound intensities are reduced substantially compared with conventional channel widths. Sound intensities are reduced further by a water spray directed immediately above the flame. Baffles placed along the top of the channel will reduce sound levels to below 90 db. Cutting rates are greater than those of existing channeling burners with costs per unit of channel area substantially reduced for those cases where oxygen costs are reasonable.
