煤炭自燃预测预报技术及其应用

Technology and application of coal spontaneous combustion prediction and forecast

在论述各种煤炭自燃预测预报技术的基础上 ,根据大屯煤矿的实际情况 ,利用三维动态数学模型预测煤炭的自然发火期和高温区域 ,用CO和C2 H4作为煤炭自燃预报的指标气体。

Based on the discuss of various technology predicting and forecasting coal spontaneous combustion, according to the practical condition of coal in Datun coal mine, a three-dimension dynamic mathematic model was used to predict the period of coal spontaneous combustion and the area of high temperature, CO and C_2H_4 were selected as the index gases forecasting coal spontaneous combustion.
