摘　　要： 以提高各标志气体对煤自然发火预报的灵敏性和可操作性为出发点,以煤升温氧化气体产物的测定实验为基础,对青山矿硬子槽各煤样产生气体量随温度的变化进行了研究.根据矿井的实际情况,引入初始化数值K,即各升温点对应的CO+CO2系列数值与CO2初值之比,确定了青山矿区大槽煤煤自燃标志气体的预报曲线和相应的拟合曲线.并采用Visual Basic语言编制相应的软件系统,该系统与束管监测系统和色谱仪组成一个全自动的煤自燃预报系统,可对矿井的煤温实行连续监控,从而提高了煤自然发火预测预报的准确性和可操作性. With the departure point of the sensitivity of each sign gas for predicting coal spontaneous combustion and operatingness, based on the measurement experiment of oxidation gas products in the process of temperatureup, researched the change curves which showed oxidation gas products of the coal samples of Yingzi coal of Qings- han Mine change with coal temperature. According to the actual condition of mine, the initial value K was led into, that was the rate of the series sums of carbon monoxide and carbon dioxide in the process of temperature-up with the initial value of carbon dioxide. Then determined the forecast curve and the corresponding fitting curve of the sign gas for predicting coal spontaneous combustion of Yingzi coal of Qingshan Mine, and the corresponding software system was worked out by using the Visual Basic language . Then a full-automatic system for predicting coal spontaneous combustion was made up which was made of the software system, the bundle pipes inspection system, and gas chromatograph . It can carry out continuous monitoring for the coal temperature of mine. So it also raises the accuracy and operatingness of predict and forecast of coal spontaneous combustion.
