Book excerpt: This study was conducted to evaluate the effectiveness of several widely used dust suppressants through quantitative field testing on two of Iowa's most widely used secondary road surface treatments: crushed limestone rock and alluvial sand/gravel. These commercially available dust suppressants included: lignin sulfonate, calcium chloride, and soybean oil soapstock. These suppressants were applied to 1000 ft test sections on four unpaved roads in Story County, Iowa.

This book was released on 2015-05-09 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the mining and processing of minerals, the mined ore undergoes a number of crushing, grinding, cleaning, drying, and product sizing operations as it is processed into a marketable commodity. These operations are highly mechanized, and both individually and collectively these processes can generate large amounts of dust. If control technologies are inadequate, hazardous levels of respirable dust may be liberated into the work environment, potentially exposing workers. Accordingly, federal regulations are in place to limit the respirable dust exposure of mine workers. Engineering controls are implemented in mining operations in an effort to reduce dust generation and limit worker exposure.

Download or read book Evaluation of Face Dust Concentrations at Mines Using Deep Cutting Practices written by Department of Health and Human Services and published by CreateSpace. This book was released on 2013-10 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dust surveys were conducted at six underground mines to determine if deep-cut mining practices expose face workers to higher levels of respirable dust by comparing levels during the first 20 ft of advance (regular-cut depth) during the deep cut to levels during the final 10 to 20 ft of advance (deep-cut depth). The studies were conducted at mines where the Mine Safety and Health Administration (MSHA) had approved an extended curtain setback distance with operation of a flooded-bed scrubber to permit taking deep cuts of up to 40 ft. In general, all of the selected mines exercised good dust control practices by maintaining water sprays, scrubber airflows, proper curtain setback distances and providing sufficient airflow to the active faces. These practices minimized variability in dust levels related to factors other than the depth of cut. To ensure proper scrubber functioning, the scrubber screen was back-flushed before commencing each cut. Both exhausting and blowing face ventilation configurations were studied. All of the operations surveyed for this study were able to successfully implement deep-cutting methods without significantly increasing the dust exposures of face workers during the cutting and bolting cycles. For exhausting face ventilation, field data indicate that scrubber airflow is the most important factor for controlling dust. Clogging of the scrubber screen can result in lower airflows; therefore, the screen must be periodically tapped and back-flushed. Data collected for this study indicate that 20-mesh screens should be cleaned for every 40 ft of advance because 22% of the deep-cut sequences surveyed for this study experienced a 20% to 35% decrease in scrubber airflow over the course of the cut. For blowing face ventilation, field and laboratory data indicate that maintaining a proper curtain-to-scrubber airflow ratio of 1.0 and a curtain setback distance that allows the miner operator to stand at the mouth of the curtain helps control dust. Curtain airflows should be measured before activation of the scrubber regardless of ventilation type (exhausting or blowing) to avoid erroneously overinflating the ratio. The curtain setback variance should be greater than the maximum cutting depth to allow miner operators to maintain their position at the mouth of the curtain when the miner is fully extended into the cut. Greater curtain setback distances associated with deep-cutting methods may result in cuts that do not require ventilation curtain, such as the initial heading developments beyond the last open crosscut. For these cuts, dust levels were generally lower during development of deep cuts when compared to regular cuts. However, adequate ventilation of cuts without ventilation curtain is dependent on a properly functioning scrubber. Dust levels on the bolting faces did not appear to be affected by the longer cycles associated with deep-cut mining practices when curtain airflow was measureable and the curtain was periodically advanced in sync with the bolting machine.
