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.

Book Synopsis Impact on Respirable Dust Levels When Operating a Flooded-Bed Scrubber in 20-Foot Cuts by : Department of Health and Human Services
Download or read book Impact on Respirable Dust Levels When Operating a Flooded-Bed Scrubber in 20-Foot Cuts written by Department of Health and Human Services and published by Createspace Independent Publishing Platform. This book was released on 2014-02-21 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Underground coal mining companies that operate continuous miner sections often apply to the Mine Safety and Health Administration (MSHA) for approval to take extended cuts to depths of up to 40 ft as a means of improving productivity. Historically, MSHA has granted approval of this practice if the mine has successfully demonstrated the ability to control the roof, methane, and respirable dust while extracting these extended cuts. A key component for controlling dust generated by continuous miners in 40-ft cuts has been the utilization of flooded-bed scrubbers. These fan-powered scrubbers pull dust-laden air from the mining face and remove respirable dust particles by passing the collected air through a wetted filter panel. The filtered air is then discharged back into the mine atmosphere. To effectively use scrubbers in faces that employ exhaust ventilation, the return ventilation curtain or tubing should be located out by the scrubber discharge on the continuous miner, which results in a setback distance from the face of approximately 40 ft. Over the last several years, MSHA has emphasized that mines demonstrate effective dust control before granting approvals for taking extended cuts with extended curtain setbacks. Each mine operator must successfully demonstrate control of workers' dust exposures in standard 20-ft cuts before MSHA considers approving extended cuts. The goal of the research conducted by the National Institute for Occupational Safety and Health (NIOSH) was to compare dust levels generated in 20-ft cuts when using traditional exhaust face ventilation without a scrubber to dust levels in 20-ft cuts when using extended curtain setbacks with a scrubber operating. Dust surveys were completed at three mines, with area and personal sampling conducted to quantify respirable dust concentrations on a cut-by-cut basis. Dust sampling results did not show a statistically significant difference in respirable dust concentrations between these two test conditions (scrubber-on and scrubber-off) at the continuous miner or shuttle car sampling locations at the face. However, with the scrubber operating, respirable dust concentrations in the return airstream downwind of the continuous miner showed reductions of 91 percent, 86 percent, and 40 percent at Mines A, B, and C, respectively. The reductions at Mines A and B were found to be statistically significant when using the Wilcoxon test. Likewise, reductions in respirable quartz dust levels in the continuous miner return were observed at all three mines, with statistically significant reductions of over 80% observed at Mines A and B. Although operation of the flooded-bed scrubber did not impact respirable dust levels in the face area, it did significantly reduce respirable and quartz dust levels downwind of the continuous miner. Consequently, operation of the flooded-bed scrubbers, in conjunction with the dust controls required in the MSHA-approved ventilation plans at these mines, was advantageous from a respirable dust control perspective.
Book Synopsis Assessment of a Continuous Miner 'wet Head' System by : B. J. Hole

Available in PDF, EPUB and Kindle. Book excerpt: Wet cutting techniques are in common use on most mining machines, being acknowledged to be the most efficient means of dust control while also being able to reduce the probability of frictional ignition. However, it is only recently that potentially reliable wet cutting systems for continuous miners have been developed. The objective of this work was to assess the practical application and implications of wet cutting systems for continuous miners working in the UK. Surface trials carried out on one such system, 'Hydraphase', demonstrated that the system could provide both effective ventilation of the cutting zone and quenching of hot ignition sources from cutter picks for the prevention of frictional ignitions, in addition to dust suppression. However, despite the phased-outlet attribute of this particular system, in which only the active two thirds of the total number of pick sprays are operated at any one instant, a total water flow of approximately 80 L/min was required to achieve these full benefits. Unfortunately, this water requirement is some three to four times that normally used on machines in the UK and is liable to present operational difficulties at many sites. either for dust control, through use of alternative sprays, or forignition prevention, by targeting particular high ignition risk areas of the cutter drum.

Available in PDF, EPUB and Kindle. Book excerpt: Continuous miners generally have flooded-bed dust scrubbers installed on them as a dust remedial tool. These scrubbers were invented in the late 1970s and their design has changed little since that time. This research will offer a redesigned, non-clogging, self-cleaning, drop-down replacement filters of the existing fibrous type screens used currently in the flooded-bed dust scrubbers on continuous miners.
