Abstract

As coal mining continues to deepen, the issue of goaf fires has become increasingly prominent, posing a significant threat to mine safety and the ecological environment. Understanding carbon dioxide (CO₂) fire prevention and extinguishing technology is crucial for preventing and controlling goaf fires. This paper explores the mechanisms of CO₂ fire prevention and extinguishing, including inertization and asphyxiation, adsorption inhibition, cooling, and explosion suppression. Additionally, it analyzes the impact of CO₂ injection locations and volume on fire prevention and extinguishing effectiveness, and outlines the advantages of using CO₂ for fire prevention and extinguishing. Furthermore, the paper proposes future research directions, such as optimizing CO₂ injection parameters, utilizing the Internet of Things to achieve intelligent management of CO₂ fire prevention and extinguishing, and exploring the synergistic application of CO₂ fire prevention and extinguishing technology with other technologies. These efforts aim to drive innovation and development in CO₂ fire prevention and extinguishing technologies, providing more efficient and sustainable solutions for coal mine safety.

期刊介绍： Thermochimica Acta publishes original research contributions covering all aspects of thermoanalytical and calorimetric methods and their application to experimental chemistry, physics, biology and engineering. The journal aims to span the whole range from fundamental research to practical application. The journal focuses on the research that advances physical and analytical science of thermal phenomena. Therefore, the manuscripts are expected to provide important insights into the thermal phenomena studied or to propose significant improvements of analytical or computational techniques employed in thermal studies. Manuscripts that report the results of routine thermal measurements are not suitable for publication in Thermochimica Acta. The journal particularly welcomes papers from newly emerging areas as well as from the traditional strength areas: - New and improved instrumentation and methods - Thermal properties and behavior of materials - Kinetics of thermally stimulated processes
