研究 C_2H_4、C_3H_6的发火速率及链烷比C_2H_6/CH_4、C_3H_8/CH_4、C_4H_(10)/CH_4,烯炔比 C_2H_4/C_2H_2等指标和煤矿自然发火的关系,已经有过不少的研究报告。但是烷烃既是煤的吸附气体成分,也在煤的氧化分解时产生,C_2H_(?)/CH_4、C_3H_8/CH_4、C_4H_(10)/CH_4随煤样升温而增大的规律是与吸附烷烃有关亦和氧化分解烷烃有关?这类烷比在常温下也随煤样存放时间延长自动增大,这与它们随煤样升温而增大的情况相
There have been many reports on the relationship between the rate of ignition of C_2H_4 and C_3H_6 and the ratio of paraffins to C_2H_6 / CH_4, C_3H_8 / CH_4, C_4H_ (10) / CH_4, alkynyl ratio C_2H_4 / C_2H_2 and spontaneous combustion in coal mines. However, the alkane is not only the adsorbed gas component of coal, but also occurs during the oxidative decomposition of coal. The law of increase of C 2 H_ (?) / CH_4, C_3H_8 / CH_4 and C_4H_ (10) / CH_4 with the increase of coal sample is related to the adsorption of alkanes And oxidative decomposition of alkanes related? This kind of alkane than at room temperature with the sample storage time automatically increases, which is with the sample temperature increases and the phase
