Abstract:
The coal seam in Shendong Mining Area is shallow depth and approximate horizontal, close interlayer spacing. The large area multilayer compound goaf will be generated after mining. Each seam has the probability of spontaneous combustion. The types of spontaneous fire are different, including close distance easy spontaneous combustion (spontaneous combustion) coal seam working face, fully mechanized roof caving spontaneous combustion (spontaneous combustion) coal seam working face, large mining height spontaneous combustion (spontaneous combustion) coal seam working face and high gas spontaneous combustion (spontaneous combustion) coal seam working face. The routine prevention and control technology roadmap was given for different spontaneous fire types to completely eradicate spontaneous fire accidents and guarantee mine safety production.
