Book Description
This book aims to understand, analyze and mitigate the harmful impacts of spontaneous coal combustion in underground mines, a thermal phenomenon that triggers fires and explosions threatening the safety of mine workers globally. Based on experimental and theoretical research findings, the book emphasizes three essential questions that are fundamental to understand spontaneous coal combustion: What are the root causes? How to evaluate the causative factors to determine the activity of coal? and How to bring this issue under control in real longwall panel? Readers are introduced to experimental techniques applied to investigate the basic molecular structure of coal and evaluate chemical properties that induce self-heating behavior, theoretical analyses to predict the extrinsic effect on low temperature oxidation of coal in experimental scale and full-size longwall panel, and preventive measures to mitigate this issue using methods for retardant screening, numerical simulations for optimal grouting and nitrogen injections, and case studies analyzing thermal events using mine atmosphere gas monitoring data. The book will be of interest to students and researchers studying mining engineering and chemistry, as well as engineers and practitioners involved in coal mine development and risk assessment.

Book Description
This comprehensive summary of the state of the art and the ideas behind the reaction engineering approach (REA) to drying processes is an ideal resource for researchers, academics and industry practitioners. Starting with the formulation, modelling and applications of the lumped-REA, it goes on to detail the use of the REA to describe local evaporation and condensation, and its coupling with equations of conservation of heat and mass transfer, called the spatial-REA, to model non-equilibrium multiphase drying. Finally, it summarises other established drying models, discussing their features, limitations and comparisons with the REA. Application examples featured throughout help fine-tune the models and implement them for process design and the evaluation of existing drying processes and product quality during drying. Further uses of the principles of REA are demonstrated, including computational fluid dynamics-based modelling, and further expanded to model other simultaneous heat and mass transfer processes.

Book Description
Naturally burning coal fires and those ignited by human activities receive little attention from the media compared to other environmental hazards, but their study is gaining ground. Here, the world's leading experts present their research findings covering topics such as the gases generated in underground coal fires, the origin of gas-vent minerals and land-cover changes due to coal fires.
