| 摘 要： | 煤炭在自燃氧化发火过程中会释放出一系列的气体,且不同阶段对应不同的气体成分和浓度,因此分析煤矿井下气体的成分及浓度可预测煤自燃的发生及发展程度。故正确的选择指标气体对预防煤炭自燃有着重要作用。结合现场取样,通过热解实验寻找适合七五煤矿3上煤层的指标气体。

| Abstract: | The coal can release a series of gas in the process of oxidation and spontaneous combustion,and different stages correspond to different gas composition and concentration.Therefore,analyzing the composition and the concentration of the gas,the occurrence and development degree of coal spontaneous combustion underground coal mine can be predicted.Thus,selecting the indicator gas accurately plays a very important role in preventing the coal spontaneous combustion.Combined with field sampling,this paper selected the suitable indicator gases for No.3 coal seam in Qiwu coal mine by the pyrolysis experiment. |
