Abstract
Aiming at the risk of existing residual coal spontaneous combustion in the goaf of the 1-2 coal seam of Dequan Coal Mine,in order to reduce the impact of the fire area on the working face stoping of the lower coal seam,a comprehensive treatment plan of air blocking,grouting fire extinguishing,and boundary sealing is proposed,and the grouting fire extinguishing effect is obvious.The research results indicate that the arranged fire extinguishing grouting drilling holes and grouting sealing drilling holes are reasonable and can effectively suppress the development of fire areas according to the high temperature area conditions in the goaf;The on-site drilling peeping measurement reveales that high concentration mud can accumulate near the roof of the roadway,indicating good fluidity and wide coverage range of yellow mud grouting;Based on the method of pipeline fans and pre embedded bundle pipes,gas monitoring and temperature monitoring are carried out on the real gas in the fire area and inside surrounding goaf.The gas temperature,CO concentration values,and its stable time all meet the requirements for fire disaster extinguishing,indicating that good fire extinguishing and leaking wind plugging effects are achieved on site.关键词
