Design and Application of KDZS-1 Multifunctional Grouting System
The design and selection of the grouting system is the key to the fire prevention and extinguishing work in coal mines.With the growth of the service life of the mine,the mine's hollow area is gradually increasing,and more reasonable grouting equipment is needed for the prevention and control of spontaneous combustion of coal seams in the hollow area.Dayun Huasheng Coal Mine upgraded and optimised the original grouting system,designed the KDZS-1 multifunctional coal mine fire extinguishing grouting system integrating material transport,mixing and grouting,and designed and calculated the grouting line and grouting volume for each coal seam.The practical results show that the CO concentration after grouting has decreased significantly,effectively solving the problems of low grouting efficiency and high cost of the original system,which has positive significance for the renovation of fire extinguishing grouting system under similar conditions.It is of positive significance for the transformation of fire prevention grouting system under similar conditions.
