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。

关键词: “三带”, 自燃, 氧气浓度, 数值拟合

Abstract: Based on the general theory Spontaneous Conbustion of coal, combining with specific situation about irregular coal working face of XINAN, design the specific Monitoring Scheme of three-zone,the paper use numerical fitting predict the distribution of three-zone according to the previous segmental measured data. In the anaphase mining, measured the distribution range of three zone, choose a point for data analysis of SPSS, the results of the analysis and prediction range high similarity. Finally, determine the distribution law of three-zone: heat release 0~12m, oxidization temperature rise 12~27m and asphyxiation above 27m.

Key words: Three-zone, spontaneous conbustion, range of oxygen concentration, numerical fitting
