Application of fire preventing and extinguishing technology in large mining height back face with broken surrounding rock
摘要
Abstract
Under the conditions of large mining height working face with the broken surrounding rock, the mining space is large, wide with broken roof, air leakage rate, especially the preventing fire in goaf during withdrawing face, is the base of realizing safety mine production. Based on the large mining height face withdrawing in Yangchangwan Coal Mine, through the use of nitrogen fire prevention and extinguishment, supplemented by traditional grouting, the wall measures, in the goaf of large mining height working face with broken surrounding rock to organize the implementation of fire prevention, and the effect of fire prevention and extinguishing are closely monitored. The field practice shows, the goaf fire in the large mining height working face could be well controlled, this process is of reference for Yangchangwan and other large mining height working face goaf fire prevention management in Ningdong mining area.关键词
