Available in PDF, EPUB and Kindle. Book excerpt: In 1980 the Bureau of Mines developed the Mine Inspection Data Analysis System (MIDAS). MIDAS is a computerized, industrial hygiene data base capable of statistically analyzing environmental data collected in coal and noncoal mines and mills by Mine Safety and Health Administration (MSHA) inspectors or mine operators. The objectives of this report are to describe the current contents of MIDAS, to report analyses of coal and noncoal mine respirable dust samples collected by MSHA inspectors and to evaluate the proposed change in the metal and nonmetal respirable dust standard from a formula based upon the percentage of quartz identified in the sample to 100 μg/m3 of respirable quartz. Based on samples collected by MSHA inspectors, changing the noncoal respirable dust standard would result in 4 pct fewer samples with dust concentrations exceeding the standard. Analysis of respirable coal dust data collected by MSHA inspectors showed that mines with longwall plows or shears had the highest geometric mean concentrations (1.64 and 1.29 mg/m3, respectively). Mine operations using continuous rippers out-numbered longwall mine operations about 10 to 1 and had a geometric mean concentration of 0.66 mg/m3.

This book was released on 2018-10-04 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coal remains one of the principal sources of energy for the United States, and the nation has been a world leader in coal production for more than 100 years. According to U.S. Energy Information Administration projections to 2050, coal is expected to be an important energy resource for the United States. Additionally, metallurgical coal used in steel production remains an important national commodity. However, coal production, like all other conventional mining activities, creates dust in the workplace. Respirable coal mine dust (RCMD) comprises the size fraction of airborne particles in underground mines that can be inhaled by miners and deposited in the distal airways and gas-exchange region of the lung. Occupational exposure to RCMD has long been associated with lung diseases common to the coal mining industry, including coal workers' pneumoconiosis, also known as "black lung disease." Monitoring and Sampling Approaches to Assess Underground Coal Mine Dust Exposures compares the monitoring technologies and sampling protocols currently used or required by the United States, and in similarly industrialized countries for the control of RCMD exposure in underground coal mines. This report assesses the effects of rock dust mixtures and their application on RCMD measurements, and the efficacy of current monitoring technologies and sampling approaches. It also offers science-based conclusions regarding optimal monitoring and sampling strategies to aid mine operators' decision making related to reducing RCMD exposure to miners in underground coal mines.

This book was released on 1970 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of its continuing program in protecting the health and safety of the nation's coal miners, the Bureau of Mines, Department of the Interior, presented on November 3-4, 1969, a Symposium on Respirable Coal Mine Dust. The Symposium was cosponsored by the American Mining Congress, the National Coal Association, and the National Independent Coal Operator's Association. Within recent years it has become evident that a large number of our coal miners develop a severe occupational respiratory disease commonly referred to as "black lung," but more appropriately designated as "coal worker's pneumoconiosis." Studies in the United States as well as in European countries clearly demonstrate that prevention of the disease is related to the control and suppression of respirable coal mine dust. This Symposium dealt with the various engineering methods of controlling dust in underground coal mines including ventialation, water suppression, machine design, and dust collection; and a discussion of respirators and life support systems. The merits of these various procedures and their potential application to underground coal mining were examined. In every case attempts were made to secure outstanding talent in each of the major areas discussed. The proceedings of the Symposium should constitue a reference on current technology for dust control. The Symposium helped to delineate those areas where additional research is needed and highlighted the necessity for concentrated efforts by both industry and Government for intensive research and investigative programs on engineering procedures to control respirable coal mine dust within prescribed hygienic limits. Hopefully, research will move so rapidly that within a reasonably short time this publication will be out of date in terms of dust control technology

Book excerpt: Book & CD. Coal mine dust is one of the most serious occupational hazards in the coal mining industry, and overexposure can cause coal workers' pneumoconiosis (CWP) and a number of other lung diseases, collectively referred to a black lung disease. CWP has been the underlying or contributing cause of death for more than 75,000 coal miners since 1968. This book provides an overview of key studies, background history and health reviews on occupational exposure to respirable coal mine dust.
