From Scotia to Brookwood, Fatal US Underground Coal Mine Explosions Ignited in Intake Air Courses


Book Description

The National Institute for Occupational Safety and Health, Pittsburgh Research Laboratory, conducted a study of past mine explosions to identify the ignition locations and ignition sources responsible for the most severe explosion events resulting in death. Since the Scotia disaster of 1976, many fatalities from underground coal mine explosions have been linked to non permissible electrical equipment ignition sources located in intake air courses. With few exceptions, explosion protected equipment is generally not required in intake air courses of gassy underground coal mines in the US. Cigarette lighters were another prevalent ignition source for fatal explosions ignited in intake air courses. Several mine rescue/recovery teams have encountered electrical ignition hazards. The study provides evidence that intake air courses of gassy underground coal mines fit the description of certain Hazardous (classified) locations described in the US National Electrical Code®. Class I Division 2 or Zone 2 explosion protection techniques may be used to design intake air equipment so that it does not present an ignition source under normal operation, before mine power is shut down in emergency situations. Non permissible circuits in intake air courses that are likely to remain energized during emergencies, e.g. battery powered equipment, should be protected by more stringent Class I Division 1, Zone 1, or Zone 0 techniques, to protect rescue/recovery personnel.




Coal and Coalbed Gas


Book Description

Bridging the gap in expertise between coal and coalbed gas, subfields in which opportunities for cross training have been nonexistent, Coal and Coalbed Gas sets the standard for publishing in these areas. This book treats coal and coalbed gas as mutually inclusive commodities in terms of their interrelated origin, accumulation, composition, distribution, generation, and development, providing a balanced understanding of this energy mix. Currently considered a non-renewable energy resource, coalbed gas, or coalbed methane, is a form of natural gas extracted from coal beds. In recent years, countries have begun to seek and exploit coal for its clean gas energy in an effort to alleviate environmental issues that come with coal use, making a book on this topic particularly timely. This volume takes into account processes of coalification, gasification, and storage and reservoir characterization and evaluation and looks at water management and environmental impacts as well. Covers environmental issues in the development of coalbed gas Includes case studies, field guides and data, examples, and analytical procedures from previous studies and investigations Accessible by a large multidisciplinary market by one of the world's foremost experts on the topic

Death Underground


Book Description

Death Underground: The Centralia and West Frankfort Mine Disasters examines two of the most devastating coal mine disasters in United States history since 1928. In two southern Illinois towns only forty miles apart, explosions killed 111 men at the Centralia No. 5 mine in 1947 and 119 men at the New Orient No. 2 mine in West Frankfort in 1951. Robert E. Hartley and David Kenney explain the causes of the accidents, identify who was to blame, and detail the emotional impact the disasters had on the survivors, their families, and their communities. Politics at the highest level of Illinois government played a critical role in the conditions that led to the accidents. Hartley and Kenney address how safety was compromised when inspection reports were widely ignored by state mining officials and mine company supervisors. Highlighted is the role of Driscoll Scanlan, a state inspector at Centralia, who warned of an impending disaster but whose political enemies shifted the blame to him, ruining his career. Hartley and Kenney also detail the New Orient No. 2 mine explosion, the attempts at rescue, and the resulting political spin circulated by labor, management, and the state bureaucracy. They outline the investigation, the subsequent hearings, and the efforts in Congress to legislate greater mine safety. Hartley and Kenney include interviews with the survivors, a summary of the investigative records, and an analysis of the causes of both mine accidents. They place responsibility for the disasters on individual mine owners, labor unions, and state officials, providing new interpretations not previously presented in the literature. Augmented by twenty-nine illustrations, the volume also covers the history, culture, and ethnic pluralism of coal mining in Illinois and the United States.

Mine Safety


Book Description

Mine Safety combines detailed information on safety in mining with methods and mathematics that can be used to preserve human life. By compiling various recent research results and data into one volume, Mine Safety eliminates the need to consult many diverse sources in order to obtain vital information. Chapters cover a broad range of topics, including: human factors and error in mine safety, mining equipment safety, safety in offshore industry and programmable electronic mining system safety. They are written in such a manner that the reader requires no previous knowledge to understand their contents. Examples and solutions are given at appropriate places, and there are numerous problems to test the reader’s comprehension. Mine Safety will prove useful for many individuals, including engineering and safety professionals working in the mining industry, researchers, instructors, and undergraduate and graduate students in the field of mining engineering.

Sustainable Management of Mining Operations


Book Description

The pressure is on to enhance corporate reputations, achieve higher operational efficiency, improve planning and control, gain access to mineral resources, build trust with stakeholders, attract financing, recruit and retain a quality workforce, and lower costs. Sustainable Management of Mining Operations provides a holistic, practical approach to achieving these goals. The key, say the authors, is to create a culture within the organization that recognizes the value of sustainability by effectively integrating economic, environmental, and social considerations. Each section of this book focuses on sustainable management from a different perspective, management level, or stage of the mine life cycle. You'll benefit from real-life, practical insights from 27 internationally respected authors whose job titles have encompassed everything from CEO to master mechanic.
