Abstract
When a coal mine fire occurs, the changing trend analysis of explosion hazard is very important to prevent secondary disasters. Nowadays, rescuers need to use various methods to analyze the explosiveness changing trend in the sealed area of a coal mine and reasons for such events, which goes against the requirements for developing explosion control measures in coal mine rapidly. Based on the Coward Triangle, this paper has established a new analysis chart and explosion tendency analysis for the changing trend of explosion hazard, which include the timeline (horizontal axis) versus explosion hazard and amount of deviation (double vertical axis). After careful comparison with other methods, results have shown that using the new method could not only effectively analyze the changing trend of explosion hazard, it could also more accurately characterize the changing trend of various gas compositions, thus providing guidance for developing rescue measures. In the end, the method is introduced which provides rough prediction for when this event might occur and time available for safe escaping in case of an explosion.
