WEN Yu;YAN Yun-long;LUO Kang-cheng;Guizhou Coal Mine Design and Research Institute;  
According to the characteristics of spontaneous combustion of coal gangue in the dump of remote coal mine in open pit mining,the technical scheme of spontaneous combustion control of coal gangue is established.First of all,the entire coal gangue yard will be covered with fire extinguishing materials(regional fire extinguishing process),which can effectively alleviate and control the spontaneous combustion fire of coal gangue yard.Then grouting is used in the deep fire point of the coal gangue yard(key fire extinguishing process),which can thoroughly control and extinguish the spontaneous combustion of coal gangue.At last,the successful practice of adopting this technology scheme on the spot has effectively extinguished the spontaneous combustion of coal gangue in the dump of open coal mine.
