Buch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book provides a scientific basis for development of targeted inhibitors and directional inhibitors of preventing spontaneous combustion of coal. This book applied solvent extraction assisted by ultrasonic into the study of coal spontaneous combustion and hence broken through the technical bottlenecks of existing studies for mechanisms of coal spontaneous combustion. Further, the theories of particles physics were firstly combined with theories of coal chemistry and finally explained some previous conjectures scientifically in this book. Thus, the theory of spontaneous combustion of coal has been greatly broadened and deepened. Moreover, a new theory named Chain self-promoted oxidizing coal spontaneous combustion theory induced by active group was proposed in this book. This theory elucidates the correlation mechanism between coal active groups and indicator gases, explaining the mechanism of indicator gas generation in coal spontaneous combustion and providing a theoretical basis for establishing an early warning indicator system for coal spontaneous combustion. This is very easy to be understood by audience with working in the field of mining or coal chemistry. Besides, principles of theories used in this book were explained in detail in this book. That is to say, there are almost no challenges or pain points for the audiences to overcome.…

Buch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book details the prevention and control of coal fire disasters. It mainly describes the occurrence and evolution mechanism of coal fire, the characteristic parameters and information recognition of coal fire and briefly introduces the detection principle, characteristics and equipment of current coal fire detection technology. Through in-depth analysis of the principle of spontaneous combustion of coal, readers can understand how underground coal fire is generated and what factors will accelerate or inhibit the combustion of coal fire. The theoretical knowledge of geophysics, geology, chemistry, sonics, quantology, and other disciplines is introduced to provide a solid theoretical basis for underground coal fire detection. For example, the location, scope, and combustion state of underground coal fire can be detected by electromagnetic method and seismic method in geophysics. The book focuses on the application methods and practical cases of various underground coal fire detection technologies, including remote sensing technology, geophysical detection technology, drilling temperature measurement technology. Of course, the latest research achievements are also introduced, including the theoretical basis and future applications of acoustic detection and quantum detection methods. Through the analysis of practical cases, readers can understand the application effects and limitations of these technologies in different regions and different geological conditions, which can provide reference for coal fire disaster detection research.…
