STUDY ON CURRENT SITUATION AND DEVELOPMENT TREND FOR COAL MINE FIRE PREVENTION TECHNOLOGY IN CHINA

摘要

The spontaneous combustion of coal seams is one of the major disasters in the mines, which seriously threatens the safe production of coal mines and endangers the safety of workers. Through the research on the current situation and development trend of coal mine fire prevention technology in China, the development history of coal mine fire prevention technology in China was traced. The basic principles and main features of coal mine fire monitoring technology, gel fire prevention technology, grouting fire prevention technology, inhibitor fire prevention technology and pressure equalization ventilation fire prevention technology were analyzed. The main achievements, applicability and existing problems of various fire prevention technologies in China were highlighted. Finally, the development direction and research trend of China's future mine fire prevention and control technology were put forward.
