摘要

针对平顶山十矿己15、己16、己17、己18煤层自然发火问题,利用程序升温氧化实验分析各煤层气体生成量变化,确定了煤层标志气体:丙烷可作为己15煤层标志气体,乙烷可作为己16煤层标志气体,CO可作为己17、己18煤层标志气体。将实验数据导入Matlab软件进行曲线拟合,得到了煤层标志气体生成量与温度之间的拟合关系式。利用现场布置的钻孔测量不同时期煤层温度及标志气体生成量,将温度测量数据代入拟合关系式,得到的标志气体生成量计算数据与实际测量数据基本一致,验证了拟合关系式的有效性。
        In view of problem of spontaneous combustion of VI-15,VI-16,VI-17 and VI-18 coal seams in Pingdingshan No.10 Coal Mine,temperature programmed oxidation experiment was used to analyze change of gas production quantity in each coal seam,and coal seam index gas were determined.Propane can be used as index gas of VI-15 coal seam,ethane can be used as index gas of VI-16 coal seam,and CO can be used as index gas of VI-17 and VI-18 coal seam.The experimental data were imported into Matlab software for curve fitting,so as to obtain fitting relationship equation between production quantity of index gas and temperature of coal seam.Temperature and production quantity of index gas of coal seam in different periods were measured through drilling holes arranged on site.The temperature measurement data were substituted into the fitting relationship equation,so as to obtain calculated data of production quantity of index gas.The calculated data is basically consistent with the actual measurement data,which verifies the validity of the fitting relationship equation.
