A filter consisting of a synthetic fibrous material has been determined to be a viable alternative to the wire mesh panels currently used in irrigated filter dust collection systems. An extensive laboratory investigation of the material showed that it removed a higher percentage of both respirable coal and quartz dust from the air entering a collector than did the flat and pleated wire mesh panel designs. This improvement in dust collection efficiency reduced the amount of coal and quartz dust discharged from the collector exhaust by approximately 44 pct. Since continued exposure to excessive levels (>5 pct) of respirable quartz dust presents a severe health hazard, this alternative filter medium could be of use to those mines required to comply with more stringent dust standards due to quartz.
