Coal refuse pile fires are a serious health, safety, and environment hazard. The fires in Guoshan Coal Refuse Pile affect daily life of the local residents. Although conventional fire control methods (water injection, grouting and surface sealing) were used to control the fires, they rekindled soon after the fire-fighting engineering was quitted. Thus, effective methods need to be applied to extinguish the fires completely without reignition. In this paper, the environmental impact of the fire on the local land, water and air is illustrated by sample analysis and photos. The self-potential method, which achieves remote detection from the ground surface, is adopted to delineate the scope of the fires to give support for the efficient and economical extinguishment of them. The three-phase foam containing water, gas and loess is proposed to control and extinguish the fires. The corresponding fire-fighting system is also invented to fit the field work and put out the fires more efficiently and conveniently. The temperature monitoring result shows that the fires are extinguished successfully with no sign of reignition.
矸石山火灾是一种严重的健康、安全和环境危害。郭山矸石山的火灾影响了当地居民的日常生活。尽管采用了注水、注浆和表面密封等常规灭火方法来控制火势，但在消防工程停止后不久，火势又重新燃起。因此，需要应用有效的方法将火完全扑灭而不重新点燃。本文通过样品分析和照片说明了火灾对当地土地、水和空气的环境影响。采用自电位法从地面进行远程探测，划定火灾范围，为高效、经济地扑灭火灾提供支持。提出了一种含有水、气和黄土的三相泡沫来控制和扑灭火灾。还发明了相应的灭火系统，以适应现场工作，更有效地扑灭火灾。温度监测结果表明，火灾已成功扑灭，无重新点燃迹象。
