Determining and Verifying the Operating Parameters of Suppression Nozzles for Belt Conveyor Drives

Drives in belt conveyors are critical components of the conveyor system, susceptible to various factors that can cause disruptions and energy losses. In underground mining conditions, risk drive fires is particularly hazardous. Therefore, it necessary develop highly effective fire suppression systems. However, there no guidelines for designing such This study presents a methodology selecting verifying systems drives. The proposed AMIGA system extinguishing on coal mine belts, incorporating spraying water mist installations, supported by theoretical calculation methodology. enables determining number required nozzles flow rate complete suppression. development selection verification sprinkler utilized provided standard VdS 2109:2002-03 PN-EN 12845+A2 from 2010, while novel approach parameters has not been previously applied anywhere else, based assessing fire’s intensity persistent disruption balance combusted coal. calculations potential power facilitate determination appropriate protect upper drive. For was calculated be 10.33MJ/min. Based this, installation established minimum 37.5dm3/min, 21.4dm3/min used space below order verify developed parameter selection, on-site tests were conducted results. Tests an prototype integrated into results demonstrate using installation, as well under within entire supply pressure range ( 0.4MPa 1.6MPa ).
