摘　　要：为了准确掌握自燃矸石山的火情规律,因地制宜地制定灭火防复燃措施,采用系统分析方法,紧密结合一座"倒坡式"堆积矸石山的治理工程,跟踪研究其火情特征,建立火情诊断程序。结果表明,矸石山的自燃发生动态历经潜伏自热、加速氧化升温和稳定燃烧3个阶段;系统内外要素相互作用使其自燃发生动态呈现复杂性和不确定性,这可通过系统分析对关键要素通风与给水状况加以控制而得到消解;对高温区内外结构分析得出其燃点大多位于坡中上部的地表下约3 m处。这种采用系统分析方法对煤矸石山火情进行诊断的思路,应成为此类矸石山治理的方向。To control the combustion rules of waste dump and take proper measures to prevent rekindling,based on the system analysismethod and project process,the fire regime characteristics of down-sloping waste dump was analysed and the fire regime systematic diagno-sis process was established as well. The research showed that the dynamics of waste dump with spontaneous combustion went through threestages which were latent self-heating,accelerated oxidation and stable combustion. Its key elements were ventilation and moisture. Theself-ignition points of high temperature zones were located in the upper slope and appeared at about 3 m apart from surface. The system a-nalysis methodology had certain reference significance for the research and control of the same type waste dump.
