Book Description
Coal mining continues to make advances, especially in the areas of safety and environmental protection as a result of mining. This book contains nine peer-reviewed articles on green coal mining that address most of the important issues associated with improving coal mining. These issues include the protection of water above coal mines, both surface and ground water, and the subsidence that occurs during and after mining with methods to limit it and methods of rehabilitation. Additional issues include mine entry and production area support and methods to control gas emissions.

Book Description
‘Coal’ and ‘China’ to some extent have become synonymous. China is by far the largest user of coal in the world. In 2016, coal production in China amounted to 3.21 billion tons, about half of the total global coal production. Coal consumption accounts for more than 65% of primary energy consumption in China. The Chinese coal industry greatly contributes to the economic development in China, the second largest economy in the world. However, periodically, ubiquitous images of smog blanketing major Chinese cities are viewed all over the world. Coal combustion is one of the important contributors to smog, which is considered to be a major environmental and human health problem for China and other countries. News stories also highlight the periodic coal mine disasters that kill hundreds of Chinese coal miners annually. The need to address these and other human health, environmental, and mine safety issues and to maximize resource recovery and use justifies a vigorous coal research effort. This book brings together experts on almost every aspect of coal geology, coal production, composition and use of the coal and its by-products, and coal’s environmental and human health impacts. The chapters in this book were originally published in a special issue of the International Geology Review.

Book Description
Coal will continue to provide a major portion of energy requirements in the United States for at least the next several decades. It is imperative that accurate information describing the amount, location, and quality of the coal resources and reserves be available to fulfill energy needs. It is also important that the United States extract its coal resources efficiently, safely, and in an environmentally responsible manner. A renewed focus on federal support for coal-related research, coordinated across agencies and with the active participation of the states and industrial sector, is a critical element for each of these requirements. Coal focuses on the research and development needs and priorities in the areas of coal resource and reserve assessments, coal mining and processing, transportation of coal and coal products, and coal utilization.

Book Description
This is an open access book.ThemeOptimizing the use of social science and economics in the post-pandemic revival era The Covid-19 pandemic is slowly starting to be overcome. Contributions from various disciplines are also needed in the context of post-pandemic recovery, including the fields of social science and economics. Thus, the International Conference on Advanced Research in Social and Economic Science is a forum for researchers and practitioners to exchange ideas and advances on how emerging research methods and sources are applied to various fields of the social sciences, as well as discuss current and future challenges. Join the social sciences conference as we explore the latest trends in social sciences and discuss common challenges in politics, social, communication, humanities, networking society, business, sustainable development, and international relations.

Book Description
This is an open access book.As society progresses and the city scale increases, architecture is diversifying and becoming complex, with structures transforming from simple structures into high-rise, long-span and even special and complex structures. Architecture is where people live and work, so its security must be ensured. However, the architectural structure is likely to be destroyed by natural disasters (earthquakes, wind, snow, rain), man-made faults and incidents (explosion, fire, crashes) and accidental events like attacks and man-made sabotage in recent years. Therefore, countries have endeavored to improve architectural security for many years. A large number of anti-seismic issues in the civil engineering construction have turned up, which also gave birth to many new anti-seismic theories, technologies and products. 2023 5th International Conference on Structural Seismic and Civil Engineering Research (ICSSCER 2023) will be held on August 25–27, 2023 in Nanjing, Jiangsu, China. With a display of the latest research outcomes in theoretical research, experimental study and engineering application, this conference creates a platform for scholars, researchers and technical personnel to exchange ideas and further understand each other. We extend a warm welcome to you and expect you to attend this academic feast to promote academic exchanges of relevant issues and advance the development of structural anti-seismic and civil engineering research and application. 2023 8th International Conference on Ecological Building and Green Building Material (EBGBM 2023,http://www.ebgbm.net/) will be conducted as a sub session of ICSSCER 2023. Scholars from home and abroad are welcomed to contribute papers and attend the conference.

Book Description
Trace Elements in Coal focuses on the compositions, reactions, and properties of trace elements in coal. The book first discusses the origin of trace elements in coal. The formation of peat; geological and geochemical aspects of coal seams; geology of Australian coals; constitution of coal; history of trace elements in coal; and coal mining in Australia are discussed. The text also clarifies the mode of occurrence of trace elements in coal. The identification of minerals in coal; silicon-rich minerals; carbonate minerals; sulfide minerals; lignites and brown coals; and phosphates are discussed. The book then underscores the methods of analysis. Inductively coupled plasma atomic emission spectrometry; atomic absorption spectrometry; spark source mass spectrometry; and neuron activation analysis are described. The text also focuses on the contents of trace elements in coal; comparisons of coal with shale and soil; relationship of radioactivity and coal; and relevance of trace elements in coal. The book is a good source of data for readers wanting to study the trace elements in coal.
