Analysis on Spontaneous Combustion of the Jurassic Coal Based on Low-temperature Oxidation

摘要

The Jurassic coal of NW China has huge recoverable reserves but large spontaneous combustion tendency. Studying on spontaneous combustion mechanism of Jurassic coal is behind of the East and north of the Carboniferous Permian. Therefore, understanding the status of fire prevention of Jurassic seam of Northwest Region is of great significance to establish research orientation of spontaneous combustion of Northwest Jurassic mines and develop the theoretical system of spontaneous combustion. The paper summarizes Jurassic coal rock features of NW China, describes in detail its low temperature oxidation characteristics of spontaneous combustion and promotes the existing spontaneous combustion model to the Jurassic coal seams. In the end, further research on laboratory studies, numerical simulation and field practice of the Jurassic coal is recommended.
