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 accident is one of the most serious disasters in coal mines, a serious threat to the safety of coal mines. By analyzing the causes of abnormal temperature anomalies in different stages of coal and gas outburst (such as stress concentration stage, rupture of coal body, gas-ruptured coal body stage, throwing out of handling stage and static desorption stage), the change of temperature of coal body is highlighted The inherent reason of danger and the feasibility of predicting coal and gas outburst by using the change of coal body temperature are analyzed. The result provides a new idea and a new method to highlight the forecast.
