There are coal seam spontaneous combustion and firing problems existing in major coal mines in China, especially in mines with a thick seam. The application of a high production and efficient mining technology in special thick seam is highly obstructed by those above problems. Therefore it is necessary to have a rapid and efficient mine fire extinguishing technology-a mine fire direct extinguishing technology with high temperature resistance high water gel to control seam spontaneous combustion and firing. The research and development of the technology is base on silicon gel to develop “setting gel", “gel mud", flying ash gel and other mine fire extinguishing materials. The materials are mainly made of basic material, accelerator, reinforcer and solution with a certain ratio blending. The mine fire extinguishing material can be transported to a mine firing site with a pipeline. The technology can be used to handle a large high temperature area in a gob area behind the hydraulic powered supports of a longwall mining face, a large area seam fire above the hydraulic powered supports and a large area high temperature and coal spontaneous combustion in a gob. This technology has successfully been applied to handle 67 mine fires.
