煤层最短自然发火期的研究

Research on Coal Seam Shortest Fire Time and its Application

目前我国对煤自然发火期建立的数学模型复杂,给定参数太多,应用起来十分困难,准确度不高;运用固相能量守恒定律判定煤炭最短发火期技术建立简便实效的数学模型,并与使用TGA/SDTA851 e同步热分析仪所得的数据进行拟合,对煤的实验最短发火期的进行测算,提高了短发火期预测的精度,对我国研究煤自燃预测预报和煤炭自燃预防具有重要的参考价值。

Nowadays,those mathematical models about coal seem shortest fire time,which have already been established,are very complex,there are so many given arguments,so it＇s very difficult to apply and have low accuracy.The technique of using solidoid conservation of energy to judge coal shortest fire time can set up simple and substantive mathematical model,and combined with the data got by using the TGA/SDTA851e Setsys Evolution,then using the result to measure the shortest time,then the accuracy of predicting the shortest fire time can be improved,and it has much reference value for forecasting and preventing coal self-heating.
