煤炭氧化后随着氧化进程的不同将依次释放出各种气体,这些气体的出现及释放量基本能准确反映煤炭氧化自燃程度。通过对煤炭自燃指标气体进行认真的分析,结合现场取样并在实验室测得的数据对淮北朱仙庄矿的气体指标进行了分析,所得结果能很好的指导矿井进行煤炭自燃的早期预测预报与防治工作。
After the oxidation of coal, the various gases will be released in turn according to the oxidation process. The appearance and release of these gases can accurately reflect the degree of spontaneous combustion of coal. Through the careful analysis of index gas of spontaneous combustion of coal and the data of on-site sampling and laboratory measurements, the gas indexes of Zhuxianzhuang coal mine in Huaibei were analyzed. The results can guide the mine in early prediction and control of coal spontaneous combustion jobs.
