Abstract

The use of high pressure water jets on roadheaders has been shown to offer several advantages including improved cutting, longer pick life, reduced incendive sparking, and better dust suppression. However, the quantity of water used by high pressure systems can lead to poor floor conditions and this has limited the application of the technique. The objective for the project was to develop a phased water system which reduced the quantity of water used, by only applying the water to that section of the cutting head which was actually in cut. The report describes the design, development and testing of a phased water system. Particular emphasis is placed on the reliability of the system and an extensive underground proving trial undertaken. A comparative study is also made between a phased and a non-phased system, with regard to the quantity of dust produced under similar operating conditions.
