Book Description
Surface-strip coal mine rehabilitation planning in South Africa and Australia is immature. Rehabilitation risk assessment, despite being advocated by leading practice guidelines and in some instances by legislation, is conducted with minimum requirements often met by rehabilitation professionals. Specialist data is gathered during mine approval and for the environmental impact assessment process. However, the focus of this is toward assessing mining impacts and not for rehabilitation risk assessment. Quantitative, integrated, multi-disciplinary rehabilitation risk assessment is seldom undertaken. This thesis provides a methodology towards the development of a quantitative, integrative, multi-disciplinary rehabilitation risk assessment model. Its purpose being to 'profile' surface-strip coal mine sites, in terms of their rehabilitation risk and potential for rehabilitation failure, from the outset of mine operations, with adjustments possible progressively during mine operations. The methodology was developed by first reviewing techniques suitable for the development of the model, as well as techniques developed by others. Bayesian networks (BN) were found to be the most suited. A R2AIN framework was then provided as a process towards developing several BN risk event models that can amalgamate to form a synthesis rehabilitation risk assessment model. A case study soil compaction BN model was used to demonstrate the framework in South Africa and Australia. The case study showed that it is possible to integrate and quantify rehabilitation risk, and most importantly to segregate risk into discrete contributing multidisciplines for analysis. Risk percentages can be calculated per multi-discipline, per mine phase, per site, to aid site risk a̲2́ƠË−profilinga̲2́Ơ4́Ø. It is recommended that further risk event BN models be prioritised for development and that a rehabilitation risk assessment model be developed to synthesise these into one model. This will require continuous improvements in the method, to build confidence, including extensive risk event and synthesis BN model evaluation and testing; improved BN input node states and values; and simplification of the conditional probability table construction method. Adaptation to other mining types, development activities and other regions should be investigated, as well as spatial linkages to geographic information systems. This research contribution improves upfront mine rehabilitation planning and decision making, providing improved tools and techniques than what currently exist.

Book Description
This book has been specially divided into studies on understanding, recognizing, evaluating and managing risk, and the issues are discussed both in theory and in practice. The design issues affecting risk are examined, and the types of ground conditions and their relative risks are compared - through both research and case histories), to make this an invaluable volume for anyone involved in ground engineering

Book Description
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.

Book Description
This report presents and discusses the consequences of selected representative failures of mine dumps of British Columbia coal mines. The consequences are subdivided into categories of impacts on the environment, the public, and mine operations. The report also discusses approaches to the application of risk analysis for mine waste dumps and makes a recommendation for development of one approach through practical applications for future mine dump designs and through consultative workshops with the mining industry. The information assembled in this report is intended to provide a basis for the objective assessment of potential impacts of future mine dump construction.

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.
