Coal mines are the main energy resources in China and play a crucial role in the development of the national economy.In the process of coal mining production,due to the influence of geo-logical and climatic factors,there are dangerous factors such as high temperature,high humidity,and high oxidation in coal mines,which pose a great threat to the life safety and production of min-ers.Therefore,strengthening the research and practice of ventila-tion safety technical measures in coal mines has important practi-cal significance and far-reaching social impact.
