摘　　要：对煤炭自然发火指标气体特性参数进行研究,能够为保障煤矿的安全高效开采提供重要的理论依据。通过实验,研究了口孜东矿13-1煤层自燃特性,以及自燃过程中生成的气体随温升的变化规律。结果表明,指标气体的比值能更好地表征煤温的大小,也更能准确地判断井下煤自燃的状态。It is very important to study the characteristics of coal spontaneous combustion index gases parameters for ensuring safe and efficient mining of coal mine.By experiment,studies the characteristic parameters of coal spontaneous combustion indicator gas of coal samples from 13-1 seam of Kouzidong coal mine,and the rules of the generated gas due to spontaneous combustion with temperature variation of spontaneous combustion of coal spontaneous combustion process.Results show that the ratio of index gases can better represent the size of the coal temperature,also can more accurately determine the underground coal spontaneous combustion state.
