摘　　要：以山西沁水煤田煤层气利用工程为例,计算了常温常压下煤层气的爆炸极限。通过对煤层气(压力为2.5 MPa,温度为200℃)中甲烷的爆炸上限的压力、温度修正计算,分析了采用压力管道输送煤层气的安全性。Taking the utilization project of coal-bed gas in Qinshui Coalfield of Shanxi Province for example, the explosive limit of coal-bed gas at normal temperature and pressure is calculated. The safety of coal-bed gas transmitted by pressure pipeline is analyzed by modifying the calculation of pressure and temperature of methane at upper explosive limit in the coal-bed gas （ pressure 2.5 MPa and temperature 200 ℃）.
