| Abstract: | Based on the limitations of mine fire prevention technology and material,the slurry of solidified fly ash was developed which could be used in extinguishing the fire happened in the top-caving tunnel.The component and character of solidified fly ash and the mobile-long-range filling technology of it were introduced.The fire-prevented theory of slurry of solidified fly ash was studied.Based on the cross-experiment,a better proportion between water and fly ash was got.After the solidified fly ash being used at the working face 2107_2 of Changcun colliery to prevent and control the top-caving fire, the trends of temperature and CO content after filling were described.The results show that the slurry of solidified fly ash is a new fire-prevent green material,and it is very suitable for fire prevention and control of top-caving tunnel in inflammable thick coal seam. |
