摘　　要：根据远程煤矿露天开采排土场煤矸石堆自燃特点,制定了排土场煤矸石自然发火防治技术方案。首先对整个煤矸石堆场采用防灭火材料覆盖灭火(区域灭火工艺),有效的缓解和控制煤矸石堆场浅部自燃火灾,然后针对煤矸石堆场深部的火源点采用灌浆灭火(重点灭火工艺),彻底控制和熄灭煤矸石堆的自燃。在现场采用该技术方案得到成功的实践,及时有效地扑灭了排土场煤矸石自燃。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.
