Exploration and application of fire prevention and extinguishing technology in shallow buried coal seams of Hongshuliang Coal Mine
Mine fire is one of the main disasters in the coal mining process and poses a serious threat to the safety of coal mine production.In order to ensure the smooth progress of mining work in Hongshuliang Coal Mine,based on the occurrence conditions of the mine itself and the nature of the coal seam,exploration are carried out on the prevention and control tech-nology of natural ignition in shallowly buried coal seams,and the application of anti-fire measures such as nitrogen injection,spraying retarder,post-mining grouting and equalization pressure are analyzed,combined with the daily fire prediction and forecast system,reasonable mining technology and ventilation system.The author puts forward a comprehensive economical and efficient fire prevention technology suitable for the mine area,which can effectively ensure the safe and smooth mining of the working face,and improve the safe production level of the mine.
