Large Scale Studies Of Spontaneous Combustion Of Coal

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.

Flammability Testing of Materials used in Construction, Transport, and Mining, Second Edition provides an authoritative guide to current best practice in ensuring fire-safe design. The book begins by discussing the fundamentals of flammability, measurement techniques, and the main types of fire tests for various applications. Building on this foundation, a group of chapters then reviews tests for key materials used in the building, transport, and mining sectors. There are chapters on wood products, external cladding, and sandwich panels as well as the flammability of walls and ceilings linings. Tests for upholstered furniture and mattresses, cables, and electrical appliances are also reviewed. A final group of chapters discusses fire tests for the transport sector, including those for railway passenger cars, aircraft, road and rail tunnels, ships, and submarines. There is also a chapter on tests for spontaneous ignition of solid materials. With its distinguished international team of contributors, Flammability Testing of Materials used in Construction, Transport, and Mining is an invaluable reference for fire safety, civil, chemical, mechanical, mining and transport engineers. In this revised edition, the latest information is provided on fire testing of products, systems, components, and materials used across these essential sectors, with all regulations and standards brought up to date. Relays all new developments in fire safety standards, regulations and performance requirements Covers a broad range of infrastructure sectors such as construction, transport, and mining Updated to include cutting-edge fire tests and the latest iteration of standards including ISO, ASTM, and EN

Coal accounts for approximately one quarter of world energy consumption and of the coal produced worldwide approximately 65% is shipped to electricity producers and 33% to industrial consumers, with most of the remainder going to consumers in the residential and commercial sectors. The total share of total world energy consumption by coal is expected to increase to almost 30% in 2035. This book describes the challenges and steps by which electricity is produced form coal and deals with the challenges for removing the environmental objections to the use of coal in future power plants. New technologies are described that could virtually eliminate the sulfur, nitrogen, and mercury pollutants that are released when coal is burned for electricity generation. In addition, technologies for the capture greenhouse gases emitted from coal-fired power plants are described and the means of preventing such emissions from contributing to global warming concerns. Written by one of the world’s leading energy experts, this volume is a must-have for any engineer, scientist, or student working in this field, providing a valuable reference and guide in a quickly changing field.
