摘    要:
本文先采用色谱-质谱联用仪定性分析了南桐煤矿三井2402煤层的煤样,在不同温度下煤炭释放出的气体组分,并用气相色谱仪测定了O_2、N_2、CH_4、CO、CO_2、C_2H_4的含量,论证了CO、C_2H_4、作为煤层自燃发火早期发现的指标气体。该指标气体,对预报井下煤炭自然发火状况,对安全生产和煤炭的开采均具有重要意义。

关 键 词:自然发火  指标气体  气相色谱分析

Abstract:
In this paper, a combined chromatograph-mass spectrometer is used to qua-litively analyse the coal samples from 2402 Coal Seam in No.3 Pit of Nantong Un derground Coal Mine and gas components emitted from coal at different temperatures. A gas chromatograph is used to measure the contents of O_2, N_2, CH_4, CO, CO_2 and C_2H_4. It have proved that CO and C_2H_4 are indicator gases to early detect self ignition of coal seams. The indicator gases are of significance to predict self-ignition of coal in underground mine, and exploit coal safetg.
Keywords:Indicator gas of self ignition   Gas Chromatography.
