“顾亭林庵中,有忠烈公祠,近岁忽地裂数尺,中有风涛声,以物探之,应手火起,至今尚然”。这是宋代鲁应龙记载的湖南嘉禾煤矿发现煤层甲烷的经过。可见自采煤工业始,人们就知道煤层中有甲烷。矿井中的甲烷常造成灾难性的事故,以天府煤矿为例,1950～1982年煤矿瓦斯突出的事故119次。因此对煤层甲烷的研究及处置方法 Gu Ting Lin Um, a loyalty martyred ancestral temple, suddenly in recent years to crack a few feet, there is wind and waves, geophysical, should start from the fire, so far still. " This is the Song Dynasty Lu Yinglong Hunan Jiahe Coal Mine methane found after the process. Visible since the coal mining industry, people know there is methane in the coal seam. Methane in mines often results in catastrophic accidents. Taking Tianfu Mine as an example, 119 coal-gas outbursts occurred from 1950 to 1982. Therefore, research on coalbed methane and disposal methods
