采场煤炭氧化自燃早期预测预报计算机数值模拟

Mathematical Models for Early Prediction of Mine Fires

本文根据在采场内促成煤炭氧化自燃的三个基本条件将其概括为三个物理量，即采场的风速、采场温度和氧的浓度，利用多孔介质渗流理论、传热学和弥散理论分别建立起来的研究三个基本物理量的数学模型及集合理论、模糊数学知识进行计算机数值模拟，根据模拟结果进行预测预报采场煤炭自燃发火程度及其时空环境的状态，从而确定控制煤炭继续加剧氧化的技术决策．

The three key parameters of mine fires are local airflow velocity,temperature and oxygen concentration. According to the theories of seepage in porous media,heat transfer and heat dispersion, mathematical models were constructed based on the three parameters. The models can be used for early prediction of mine fires and for estimation of the lecel of spontaneous combustion.Proper use of the models can assist preventing and controlling mine fires.
