摘要
阿拉德磷酸盐矿山在开采过程中,大量的油页岩作为剥离物,被就近堆放到排土场,由于当地气候炎热、降水量少,排土场的自燃发火现象比较严重,对边坡稳定、安全生产、以及周边生态环境产生了严重的影响,针对油页岩的自燃特性,提出灭火措施,为矿山的正常有序生产,提供了保障。
In the mining process, a large number of oil shale as debris in Allard phosphate mine are piled up to the nearest dump. Because of the hot climate and less precipitation, the spontaneous combustion phenomenon of dump is more serious, which has severe effect on the slope stability, safety production and ecological environment. According to the spontaneous combustion characteristics of oil shale, the article presents outfire measures, which provides the guarantee for the normal production in mines.
