摘　　要：介绍了在松藻矿务局石壕煤矿ＴＦ－２００型煤矿环境监测系统上，以增挂ＣＯ、Ｏ２等火灾预报参量传感器并配备专用微机及数据处理软件建立的煤自然发火时间预测系统，在观测割煤、放炮、外因火灾及工作面风量变化时，火灾预报参量的波动规律；提出了以拉依达法为基础的数据处理方法。现场数据处理实例表明，所提出的数据处理方法能消除火灾预报参量的异常波动数据，使火灾预报参量变化趋势曲线更具规律性。Abstract A forecasting system for spontaneous combustion time was set up in Shihao Coal Mine of Songzao Minging Administration by adding CO and O2 sensors to TF-200 environmnet monitoring system and equipped with a special computer and data processing software.Fluctuation rule of the parameters for fire prediction was observed in coal cutting,blasting,external fire and change of air quantity at face by the system,a data processing method was proposed based on Raita method.It is shown by the field case of data processing that the proposed data processing method can eliminate abnormal fluctuation of the parameters for fire prediction and the curve of changing tendency of the parameters is more regular,thus raising the precision of fire prediction.\;
