摘　　要：煤与瓦斯突出事故是煤矿最严重的灾害之一,严重威胁着煤矿的安全生产。通过分析煤与瓦斯突出过程中不同阶段(应力集中阶段、煤体破裂阶段、瓦斯撕裂煤体阶段、抛出搬运阶段及静态解吸阶段)的温度异常变化原因,探讨了煤体温度变化与突出危险的内在原因,分析了利用煤体温度变化预测预报煤与瓦斯突出的可行性,为突出预测预报提供一种新思路和新方法。Coal and gas outburst is one of the most serious disasters in coal mines,which threatens the safety production severly.Through analyzing the temperature abnormal change causes of the different phase： stress concentration,coal rupture,gas tearing coal,throwout carry and static desorption phase,the internal causes of coal temperature change and outburst danger are discussed.The feasibility of coal and gas outburst with coal temperature change is analyzed.A kind of new clue and way is provided for outburst prognosis.
