摘要
Abstract
Baijiao Coal Mine is very close and easy spontaneous combustion coal seam,and 2464 coal mining face had serious spontaneous combustion hidden trouble in the beginning of mining.By taking measures such as filling liquid carbon dioxide after successfully controlling risk development,CO concentration is high during the late period of mining and withdrawing.From coal seam spontaneous combustion tendency,and high level residual coal,and early spontaneous combustion,and geological structure and other aspects,we analyze the risk of spontaneous combustion during the late mining and withdraw of the working face.Through taking a series of protective measures for fire-fighting techniques including strengthening monitoring forecast,speeding up mining speed,inerting gob,reducing air leakage and improving back withdrawal process,the CO concentration in goaf is stable,which ensures that the working face is retreated and closed after withdrawing.关键词
