摘要
系统阐述了煤层自燃机理的各种学说；详细介绍了自燃倾向性测试法、综合因素评价法、统计经验法、数学模型及数值模拟等煤层自燃预测方法；同时综述了标志气体分析法、测温法、红外探测法等多种煤层自燃预报方法。
Spontaneous combustion of coal seam affects the safe and high - efficiency mining seriously. Based on the present research fruits, all kinds of ideas on spontaneous combustion mechanism of coal seam were summarized. The corresponding prediction techniques for spontaneous combustion of coal seam were analyzed systematically, including spontaneous combustion tendency test, integrating all the relevant factors estimation, statistic and empirical method, and mathematical model ＆ numerical simulation method. The forecast methods were also brought forward, such as significant gas analysis, temperature measuring, infrared temperature measuring, etc. At last, some prospects over the prediction and forecast techniques of coal seam spontaneous combustion were put forward. These are of great significance for coal safety production.
