Book Description
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.

Book Description
Combustion, Flames, and Explosions of Gases, Second Edition focuses on the processes, methodologies, and reactions involved in combustion phenomena. The publication first offers information on theoretical foundations, reaction between hydrogen and oxygen, and reaction between carbon monoxide and oxygen. Discussions focus on the fundamentals of reaction kinetics, elementary and complex reactions in gases, thermal reaction, and combined hydrogen-carbon monoxide-oxygen reaction. The text then elaborates on the reaction between hydrocarbons and oxygen and combustion waves in laminar flow. The manuscript tackles combustion waves in turbulent flow and air entrainment and burning of jets of fuel gases. Topics include effect of turbulence spectrum and turbulent wrinkling on combustion wave propagation; ignition of high-velocity streams by hot solid bodies; burners with primary air entrainment; and description of jet flames. The book then takes a look at detonation waves in gases; emission spectra, ionization, and electric-field effects in flames; and methods of flame photography and pressure recording. The publication is a valuable reference for readers interested in combustion phenomena.

Book Description
Sensing and Monitoring Technologies for Mines and Hazardous Areas: Monitoring and Prediction Technologies presents the fundamentals of mining related geotechnical risk and how the latest advances in sensing and data communication can be used both to prevent accidents and provide early warnings. Opencast mining operations involve huge quantities of overburden removal, dumping, and backfilling in excavated areas. Substantial increases in the rate of accumulation of waste dumps in recent years has resulted in greater height of dumps and also has given rise to the danger of dump failures as steeper open pit slopes are prone to failure. These failures lead to loss of valuable human lives and damage to mining machinery. This book presents the most recent advances in gas sensors, methane detectors, and power cut-off systems. It also introduces monitoring of the gas strata and environment, and an overview of the use of Internet of Things and cloud computing for mining sensing and surveillance purposes. Targeted at geotechnical and mining engineers, this volume covers the latest findings and technology to prevent mining accidents and mitigate the inherent risk of the activity. - Presents complete details of a real-time slope stability monitoring system using wireless sensor networking and prediction technique based on multivariate statistical analysis of various parameters and analytical hierarchy process methods - Discusses innovative ideas and new concepts of sensing technologies, mine transport surveillance, digital mining, and cloud computing to improve safety and productivity in mining industry - Includes slope stability prediction software, downloadable through a companion website, which can be used for monitoring, analyzing, and storing different sensors and providing audio-visual, SMS, and email alerts - Covers the latest findings and technology to prevent mining accidents and mitigate the inherent risk

Book Description
In the late 1870s, Jefferson County, Alabama, and the town of Elyton (near the future Birmingham) became the focus of a remarkable industrial and mining revolution. Together with the surrounding counties, the area was penetrated by railroads. Surprisingly large deposits of bituminous coal, limestone, and iron ore—the exact ingredients for the manufacture of iron and, later, steel—began to be exploited. Now, with transportation, modern extractive techniques, and capital, the region’s geological riches began yielding enormous profits. A labor force was necessary to maintain and expand the Birmingham area’s industrial boom. Many workers were native Alabamians. There was as well an immigrant ethnic work force, small but important. The native and immigrant laborers became problems for management when workers began affiliating with labor unions and striking for higher wages and better working conditions. In the wake of the management-labor disputes, the industrialists resorted to an artificial work force—convict labor. Alabama’s state and county officials sought to avoid expense and reap profits by leasing prisoners to industry and farms for their labor. This book is about the men who worked involuntarily in the Banner Coal Mine, owned by the Pratt Consolidated Coal Company. And it is about the repercussions and consequences that followed an explosion at the mine in the spring of 1911 that killed 128 convict miners.

Book Description
Ninety-nine men entered the cold, dark tunnels of the Consolidation Coal Company's No.9 Mine in Farmington, West Virginia, on November 20, 1968. Some were worried about the condition of the mine. It had too much coal dust, too much methane gas. They knew that either one could cause an explosion. What they did not know was that someone had intentionally disabled a safety alarm on one of the mine's ventilation fans. That was a death sentence for most of the crew. The fan failed that morning, but the alarm did not sound. The lack of fresh air allowed methane gas to build up in the tunnels. A few moments before 5:30 a.m., the No.9 blew up. Some men died where they stood. Others lived but suffocated in the toxic fumes that filled the mine. Only 21 men escaped from the mountain. No.9: The 1968 Farmington Mine Disaster explains how such a thing could happen--how the coal company and federal and state officials failed to protect the 78 men who died in the mountain. Based on public records and interviews with those who worked in the mine, No.9 describes the conditions underground before and after the disaster and the legal struggles of the miners' widows to gain justice and transform coal mine safety legislation.

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
