七星矿煤样不同粒度在不同温度下的耗氧特性研究

The research of the characteristic of oxygen consumption of The QIXING Mining coal in different temperature

通过对七星煤矿煤样的程序升温实验,可测定不同温度时不同粒度煤样的氧气消耗量,研究发现不同粒度煤样的耗氧速度随温度的变化关系比较好的符合指数函数关系,拟合不同煤样的实验数据得出了煤样的耗氧速度与温度的函数关系,揭示出了煤样耗氧速度与温度的内在关系,为研究煤的氧化特性,煤的自燃特性提供了参考,为煤矿预防煤层的自燃发火灾害提供了帮助。

The QIXING Mining coal was programmed temperature experiment, in different temperature the oxygen consumption was mensurated. Through analyzing the relation between the rate of oxygen consumption and temperature, index function was discovered. And index function curve simulated the relation, so the results can direct the prevention and treatment of fire in mine.
