This book is titled "Research on the Control Theory and Application of Coal Mine Gas Treatment Process", aiming to explore the control theory, methods, intelligent support systems, and practical applications in the coal mine gas treatment process. The book is divided into five chapters, covering basic research, technical applications, case studies, and accident case analysis of coal mine gas control. The first chapter is an introduction, mainly summarizing the theory of coal mine gas control process control and exploring relevant research methods. Chapter 2 is the basic research section, focusing on the construction and evaluation of the coal mine gas safety situation indicator system, analysis of accident causing factors and prevention and control technologies, as well as the construction and research of a comprehensive evaluation model for safety investment. Chapter 3 is the technical application section, mainly studying the concentration monitoring and data analysis of coal mine gas, the preprocessing methods of coal mine gas monitoring data, as well as the multi-sensor information fusion system structure and alarm signal identification of gas monitoring. The fourth chapter is the case study and practical application part, taking Yonghong Coal Mine, Dawan Coal Mine, and Tingnan Coal Mine as examples to explore gas storage and drainage methods, gas prevention and control technology demonstration and practice, as well as the comprehensive gas control technology and effectiveness evaluation of 204 working face based on FLAC3D. Chapter 5 is the accident case analysis and evaluation section, which compares and analyzes the causes of unsafe actions in coal mine gas explosion accidents between China and the United States. It also explores the laws and preventive measures of coal mine accidents in Ningxia, as well as the identification and evaluation of human error hazards in coal mines based on Bayesian networks. This book aims to provide theoretical basis and practical guidance for research in the field of coal mine gas control, provide technical support for coal mine safety production, and provide effective ways to reduce the occurrence of coal mine gas accidents. 

I hope this book can provide useful reference and assistance for research and practice in the field of coal mine gas control. Due to the wide range of fields involved in the process control theory and its application of coal mine gas control, there are inevitably shortcomings in the book. We kindly request criticism and correction from readers.
