Download or read book Explosion Effects on Mine Ventilation Stoppings written by Department of Health and Human Services and published by CreateSpace. This book was released on 2013-10 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Institute for Occupational Safety and Health (NIOSH) and the Mine Safety and Health Administration (MSHA) conducted joint research to evaluate explosion blast effects on typical U.S. mine ventilation stoppings in the NIOSH Pittsburgh Research Laboratory's (PRL) Lake Lynn Experimental Mine (LLEM). An innovative Australian-designed brattice stopping was also evaluated. After mine explosion accidents, MSHA conducts investigations to determine the cause(s) as a means to prevent future occurrences. As part of these postexplosion investigations, the condition of underground stoppings, including the debris from damaged stoppings, is documented as evidence of the approximate strength and the direction of the explosion forces. Permanent stoppings are used to control and direct the ventilation airflow through underground coal mines to dilute and render harmless methane, entrained coal dust, and other contaminants at the working face and other areas of the mine. 30 CFR 75.333 requires that permanent stoppings be built and maintained between intake and return air courses beginning at the third connecting crosscut outby the working face and to separate other air courses and direct air as specified. To perform the intended function and meet the requirements of 30 CFR 75.333, permanent stoppings are to be constructed in a traditionally accepted method and of materials that have been demonstrated to perform adequately or in a method and of materials that have been tested and shown to have a minimum strength equal to or greater than the traditionally accepted in-mine controls. A few examples of traditionally accepted [61 Fed. Reg. 9764 (1996)] stopping construction methods are as follows: (1) 8-in (20-cm) and 6-in (15-cm) concrete block (both hollow-core and solid) with mortared joints, (2) 8-in (20-cm) and 6-in (15-cm) concrete blocks, dry-stacked and coated on one or both sides with a strength-enhancing sealant suitable for dry-stacked stoppings, and (3) steel stoppings (minimum 20-gauge) with seams and perimeter sealed with a suitable mine sealant. Unlike mine ventilation seal structures that are commonly used to isolate unused sections of the mine, stoppings are not intended to withstand explosion overpressures. Unfortunately, mine explosions do occur. Depending on the location and severity, explosions can result in fatalities and injuries to underground mining personnel and cause considerable underground damage to equipment and structures. In the mine explosions in Alabama in 2001 and West Virginia in 2006, ventilation stoppings were destroyed. Mine Safety and Health Administration (MSHA) personnel conduct investigations into these types of explosion accidents to determine the root cause(s) as a means to prevent future occurrences. As part of postexplosion investigations, the location and condition of underground ventilation structures and debris are mapped. This information helps the investigators determine the strength and the direction of the forces of the explosion.

Download or read book Risk Analysis of Vapour Cloud Explosions for Oil and Gas Facilities written by Guowei Ma and published by Springer. This book was released on 2019-05-11 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on describing and applying risk analysis of vapour cloud explosions (VCEs) in various oil and gas facilities, such as petrol stations, processing plants, and offshore platforms. Discussing most of the complicated features of gas explosion accidents, the book studies in detail the gas explosion risk analysis approaches of different oil and gas facilities in order to develop more accurate, detailed, efficient and reliable risk analysis methods for VCEs under different conditions. Moreover, it introduces an advanced overpressure approach to predict VCEs using computational fluid dynamics (CFD) modelling, and details applications of CFD using a FLame ACceleration Simulator (FLACS). The book is intended for researchers and organisations engaged in risk and safety assessments of VCEs in the oil and gas industry.
Download or read book Explosions in Underground Coal Mines written by Jianwei Cheng and published by Springer. This book was released on 2018-03-23 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the hazard of gas explosions in sealed underground coal mines, and how the risk of explosion can be assessed, modeled, and mitigated. With this text, coal mine operators and managers will be able to identify the risks that lead to underground mine gas explosions, and implement practical strategies to optimize mining safety for workers. In six chapters, the book offers a framework for understanding the sealed coal mine atmosphere, the safety characteristics that are currently in place, and the guidelines to be followed by engineers to improve upon these characteristics. The first part of the book describes the importance and characteristics of underground gas mine explosions in a historical context with data showing the high number of fatalities from explosion incidents, and how risk has been mitigated in the past. Chapters also detail mathematical models and explosibility diagrams for determining and understanding the risk factors involved in mine explosions. Readers will also learn about safety operations, and assessments for the sealed mine atmosphere. With descriptions of chapter case studies, mining engineers and researchers will learn how to apply safety measures in underground coal mines to improve mining atmospheres and save lives.

Download or read book How Tobacco Smoke Causes Disease written by United States. Public Health Service. Office of the Surgeon General and published by . This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.
Download or read book Hendrik Petrus Berlage written by Hendrik Petrus Berlage and published by Getty Publications. This book was released on 1996-01-01 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hendrik Petrus Berlage, the Dutch architect and architectural philosopher, created a series of buildings and a body of writings from 1886 to 1909 that were among the first efforts to probe the problems and possibilities of modernism. Although his Amsterdam Stock Exchange, with its rational mastery of materials and space, has long been celebrated for its seminal influence on the architecture of the 20th century, Berlage's writings are highlighted here. Bringing together Berlage's most important texts, among them "Thoughts on Style in Architecture", "Architecture's Place in Modern Aesthetics", and "Art and Society", this volume presents a chapter in the history of European modernism. In his introduction, Iain Boyd Whyte demonstrates that the substantial contribution of Berlage's designs to modern architecture cannot be fully appreciated without an understanding of the aesthetic principles first laid out in his writings.
