Compiled via the U.S. Dept of healthiness and Human companies, CDC/NIOSH place of work of Mine safeguard and future health learn, this 2010 guide used to be constructed to spot on hand engineering controls which could support underground and floor metal/nonmetal mining operations in lowering employee publicity to respirable silica dirt. The controls mentioned during this guide variety from long-used controls that have constructed into criteria, to more moderen controls, that are nonetheless being optimized

In one case, a worker performs the bag stacking task manually but is assisted by using a hydraulic lift table. This lift table allows the height for stacking the bags to remain constant throughout the entire pallet loading cycle. The bag loading height is set to approximately knuckle-high for the worker, which is the most ergonomic loading height. A push-pull ventilation system is used on either side of this pallet (Figure 4-14) to capture the dust liberated during bag stacking processing [USBM 1988a, 1989].

This plastic stripping employs an overlapping sequence which provides for a very effective seal (Figure 4-2). One noteworthy benefit to the plastic stripping is that the panels are not damaged if contacted by the bucket of the front-end loader or the bed of the haul truck during dumping. • Filter. When using an enclosure, it is also possible to incorporate a local exhaust ventilation (LEV) system to filter the dust-laden air from the hopper area. This would be most applicable when the primary dump is at a location where the dust could enter an adjoining structure or impact outside miners.
