摘　　要：基于煤体自燃的一般理论,结合鑫安煤矿1307刀把工作面的特殊情况,设计了具体的＂三带＂监测方案,根据前期部分实测数据并结合数值拟合的方法预测了工作面采空区＂三带＂的分布规律。后期回采过程中进一步现场实测了＂三带＂的分布范围,选取D1测点对数据进行Spss分析,分析结果与预测范围相似度极高,最终确定＂三带＂的分布范围：散热带0-12m,自燃带12-27m,窒息带大于27m。Based on the general theory of coal spontaneous combustion,a three- zone monitoring scheme was designed,combining with the situation of irregular coal working face in Xin＇an coal mine,the distribution of three- zone was predicted with numerical fitting according to measured data.The distribution range of three- zone was measured during mining process,the data of D1 station was chosen for SPSS analysis,the prediction result was very close to analysis result.The distribution of three- zone was：heat release zone 0 - 12 m,oxidization zone 12 - 27 m and choking zone above 27 m.
