Improving Self Escape From Underground Coal Mines

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.

Section 2 of the Mine Improvement and New Emergency Response Act of 2006 (2006 MINER Act), Public Law 109-236, [MINER Act 2006] directed operators of underground coal mines to improve accident preparedness and response. This report summarizes the findings of research conducted by the National Institute for Occupational Safety and Health (NIOSH) between December 2007 and March 2009 to identify the attributes of an improved escape and rescue system. This report focuses on specific guidelines for escape and rescue from underground coal mines during fire and explosion incidents and contains an investigation of United States and worldwide mine practices. The basic elements of a mine emergency response system (escape, rescue, and incident command) are addressed. Further, knowledge gaps, training, human behavior, and technology challenges are also identified. This report presents a strategy of self-escape and safe-rescue including incident command as an integrated system with consideration given to U.S. underground coal mine demographics. The findings are intended to facilitate the evolution of all miners' capabilities and support institutions so that they will have a greater chance of successfully managing abnormal incidents without injury or fatalities.

Human-Centered Design for Mining Equipment and New Technology first introduces Human-Centered Design (HCD) and outlines the benefits of this approach for mining equipment and new technology: HCD is a process that aims to make equipment and systems more usable and acceptable by explicitly focusing on the end-user, their tasks and their work environment/use context. The book outlines three linked areas of mining HCD: key principles, examples of design processes, and what kinds of tools for data collection and evaluation are available. The possible future uses of Human-Centered Design in more fully automated mining are presented, and the role of HCD within wider human system integration are outlined. The ‘how to’ nature of this book makes it attractive to mining equipment manufacturers, technology developers, mine site personnel, human factors researchers, safety scientists and regulators. Features: Includes an introduction useful to anyone wanting to learn about the field Provides extensive case studies of HCD which also show failures when HCD was not considered Covers cutting edge mining technology- such as proximity detection devices and new mining automation systems Directly outlines the benefits of HCD for the minerals industry Human-Centered Design for Mining Equipment and New Technology, through case studies, provides a much needed guide to undertaking HCD for mining equipment and new technology.

Mine workers' self-escape competencies (SEC) need to be better assessed during mine safety training to be sure that every underground mine worker possesses the competencies needed to successfully escape from emergencies that could occur in their mine. In response, researchers from the National Institute for Occupational Safety and Health (NIOSH) sought to learn how mine safety trainers are teaching and assessing SEC in mine safety training. To accomplish their objectives, NIOSH researchers completed in-depth interviews with nine coal mine safety trainers about teaching and assessing SEC. Based on the results of these interviews, recommendations are provided in this document for mine safety trainers and mine operators to improve the training, assessment, and maintenance of SEC.
