Conveyor belting suspended along the length of the splitter arm, along with the directional sprays, helps split the airflow coming down the face. The belting also provides a physical barrier between the face conveyor and walkway, which helps prevent dust from moving into the walkway. Tears and gaps in the conveyor belting greatly compromise the effectiveness of the splitter arm. Locating sprays on the walkway side of the splitter arm and directing the sprays down the side of the belting (Figure 3-9) may help limit dust migration into the walkway. High-capacity, low-pressure, flat-fan sprays spaced evenly along the length of the splitter arm and directed down the side of the belting can block any fugitive dust from escaping beyond the splitter arm.
