Book Description
"Respirable dust exposure has long been known to be a serious health threat to workers in many industries. In coal mining, overexposure to respirable coal mine dust can lead to coal workers' pneumoconiosis (CWP). CWP is a lung disease that can be disabling and fatal in its most severe form. In addition, miners can be exposed to high levels of respirable silica dust, which can cause silicosis, another disabling and/or fatal lung disease. Once contracted, there is no cure for CWP or silicosis. The goal, therefore, is to limit worker exposure to respirable dust to prevent development of these diseases. The passage of the Federal Coal Mine Health and Safety Act of 1969 established respirable dust exposure limits, dust sampling requirements for inspectors and mine operators, a voluntary x-ray surveillance program to identify CWP in underground coal miners, and a benefits program to provide compensation to affected workers and their families. The tremendous human and financial costs resulting from CWP and silicosis in the U.S. underground coal mine workforce are shown by the following statistics: 1. During 1970-2004, CWP was a direct or contributing cause of 69,377 deaths of U.S. underground coal mine workers. 2. During 1980-2005, over $39 billion in CWP benefits were paid to underground coal miners and their families. 3. Recent x-ray surveillance data for 2000-2006 show an increase in CWP cases. Nearly 8% of examined underground coal miners with 25 or more years of experience were diagnosed with CWP. 4. "Continuous miner operator" is the most frequently listed occupation on death certificates that record silicosis as the cause of death. In light of the ongoing severity of these lung diseases in coal mining, this handbook was developed to identify available engineering controls that can help the industry reduce worker exposure to respirable coal and silica dust. The controls discussed in this handbook range from long-utilized controls that have developed into industry standards to newer controls that are still being optimized. The intent was to identify the best practices that are available to control respirable dust levels in underground and surface coal mining operations. This handbook provides general information on the control technologies along with extensive references. In some cases, the full reference(s) will need to be consulted to gain in-depth information on the testing or implementation of the control of interest. The handbook is divided into five chapters. Chapter 1 discusses the health effects of exposure to respirable coal and silica dust. Chapter 2 discusses dust sampling instruments and sampling methods. Chapters 3, 4, and 5 focus on dust control technologies for longwall mining, continuous mining, and surface mining, respectively. Finally, it must be stressed that after control technologies are implemented, the ultimate success of ongoing protection for workers depends on continued maintenance of these controls. NIOSH researchers have often seen appropriate controls installed, but worker overexposures occurred because of the lack of proper maintenance of these controls." - NIOSHTIC-2

Book Description
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 Description
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.

Book Description
The Office of Industrial Technologies (OIT) of the U. S. Department of Energy commissioned the National Research Council (NRC) to undertake a study on required technologies for the Mining Industries of the Future Program to complement information provided to the program by the National Mining Association. Subsequently, the National Institute for Occupational Safety and Health also became a sponsor of this study, and the Statement of Task was expanded to include health and safety. The overall objectives of this study are: (a) to review available information on the U.S. mining industry; (b) to identify critical research and development needs related to the exploration, mining, and processing of coal, minerals, and metals; and (c) to examine the federal contribution to research and development in mining processes.
