Study on comprehensive prevention and control technology of spontaneous combustion in goaf of Nalinmiao mine

Yan Min-jie

Abstract

According to the spontaneous combustion tendency of the No.6-2 seam in Nalinmiao Mine,base on the analysis on the conditions and causes of the spontaneous combustion in the goaf,the correct selected mine development and mining method,optimized mine ventilation system,enhanced goaf sealing,rapid mine gateway driving,falling coal left reduction,falling coal oxidized prevention and other comprehensive technical measures were set up.With the above measures implemented,the spontaneous combustion occurred in the goaf could be eliminated at the certain temperature.
