Compiled through the U.S. Dept of well-being and Human companies, CDC/NIOSH place of work of Mine defense and wellbeing and fitness examine, this 2010 guide used to be built to spot to be had engineering controls that could support underground and floor metal/nonmetal mining operations in lowering employee publicity to respirable silica airborne dirt and dust. 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

The above research findings also suggest that the use of a one-directional airflow pattern could be beneficial. In most systems, both the intake and discharge for the recirculation air are located in the roof. This could cause a portion of the air to short-circuit without penetrating deeply into the cab. Also, as cab air is drawn into the ventilation system at the roof, dust generated in lower portions of the cab may be pulled through the breathing zone of the worker. In a one-directional design, recirculated air is drawn from the bottom of the enclosure and away from the worker’s breathing zone.

Some studies have shown that the oversized material is more easily removed through scraping but the smaller respirable-sized particles tend to remain adhered to the conveyor. When this occurs, a belt wash should be installed. A belt wash sprays the conveyor belt with water while simultaneously scraping it to remove 33 the product. In a number of published studies in this area, this technique has been shown to increase the cleaning effectiveness by approximately 14% [Planner 1990]. • Effective belt loading.

Not only is the initial cost of this technique inexpensive when compared to the other engineering controls, the operation and maintenance are also minimal. To further reduce their costs, operations can potentially install all the components for this system with in-house personnel. Therefore, the TMVS can be a very cost-effective system to lower respirable dust levels at mineral processing operations [Cecala 1998; Cecala and Thimons 1997; Cecala, et al. 1996]. Figure 4-9. Design concept of TMVS showing clean-air intakes and dust-laden air exhausts.
