Coal mine disasters in the United States are relatively rare events; many of the roughly 50,000 miners underground will never have to evacuate a mine in an emergency during their careers. However, for those that do, the consequences have the potential to be devastating. U.S. mine safety practices have received increased attention in recent years because of the highly publicized coal mine disasters in 2006 and 2010. Investigations have centered on understanding both how to prevent or mitigate emergencies and what capabilities are needed by miners to self-escape to a place of safety successfully. This report focuses on the latter - the preparations for self-escape. In the wake of 2006 disasters, the U.S. Congress passed the Mine Improvement and New Emergency Response Act of 2006 (MINER Act), which was designed to strengthen existing mine safety regulations and set forth new measures aimed at improving accident preparedness and emergency response in underground coal mines. Since that time, the efforts of the National Institute of Occupational Safety and Health (NIOSH) and the Mine Safety and Health Administration (MSHA) have contributed to safety improvements in the mining industry. However, the Upper Big Branch mine explosion in 2010 served as a reminder to remain ever vigilant on improving the prevention of mine disasters and preparations to help miners survive in the event of emergencies. This study was set in the context of human-systems integration (HSI), a systems approach that examines the interaction of people, tasks, and equipment and technology in the pursuit of a goal. It recognizes this interaction occurs within, and is influenced by, the broader environmental context. A key premise of human-systems integration is that much important information is lost when the various tasks within a system are considered individually or in isolation rather than in interaction with the whole system. Improving Self-Escape from Underground Coal Mines, the task of self-escape is part of the mine safety system.

"Mine explosions remain a threat to underground coal miners, requiring constant vigilance to prevent accumulations of combustible gasses and dusts and to limit sources of ignition. Accumulations of combustible dust in coal mines create the risk of large-scale explosions that can result in multiple deaths and traumatic injuries. The explosion hazard can be effectively controlled through the application of rock dust, such as limestone dust, to render inert the combustible coal dust generated during the mining and transport of coal (see publication 2011-196 at www.cdc.gov/niosh/docs/impact). Traditionally, determining when additional rock dust should be applied or evaluating the effectiveness of existing rock dust application has been limited to a subjective visual evaluation or to the collection and laboratory analysis of dust samples - a process that requires days or weeks to identify a hazard. For decades, miners have been able to monitor the concentrations of methane and other combustible gasses using handheld, direct reading gas detectors. These detectors have allowed miners to take immediate action to dilute gasses and prevent explosions. With this same purpose in mind, researchers at the National Institute for Occupational Safety and Health (NIOSH) developed a real-time dust explosibility measuring instrument to provide instant feedback to miners on the relative hazard of dust accumulations in the mine and the effectiveness of their rock dusting practices. This instrument, the Coal Dust Explosibility Meter (CDEM), is a simple-to-use handheld device that provides a pass/fail assessment of coal mine dust samples. With this device, miners, mine operators and regulators will have the information necessary to take immediate action to eliminate an explosion hazard." - NIOSHTIC-2

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.

Widespread explosions in coal mines can be prevented if rock dust of suitable size and composition is applied effectively within two or three cuts of face; distance between end of rock dusting and face should never exceed 80 feet. Water should be used on cutter bar of mining machines, and coal piles and should not only be wetted after blasting but kept wet during landing.
