全球范圍內(nèi)采煤每年釋放的甲烷量約49Mt，約占全球范圍內(nèi)甲烷排放總量的9％左右。甲烷在大氣中的濃度是各溫室氣體中增長(zhǎng)最快的一個(gè)。因其強(qiáng)烈的溫室效應(yīng)，甲烷的排放必須受到有效的控制?？傮w上看，礦井乏風(fēng)中的甲烷及礦井煤層氣抽放過(guò)程中所抽出的濃度<35％的煤層氣基本上被排入大氣，尤其是礦井乏風(fēng)中的甲烷因其極低的濃度，基本上沒(méi)有有效的利用途徑。這些被排入到大氣中的甲烷不僅造成嚴(yán)重的大氣污染，而且極大地浪費(fèi)了能源。

The annual release of methane from coal mining worldwide is about 49Mt, accounting for approximately 9% of the total methane emissions worldwide. The concentration of methane in the atmosphere is the fastest growing among all greenhouse gases. Due to its strong greenhouse effect, methane emissions must be effectively controlled. Overall, methane in mine exhaust and coalbed methane extracted during the extraction process with a concentration of less than 35% are basically discharged into the atmosphere, especially methane in mine exhaust, which has an extremely low concentration and basically no effective utilization pathway. These methane emissions into the atmosphere not only cause serious air pollution, but also greatly waste energy.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed the "Shimadzu 2014 5A Chromatography Column Application for Mine Gas Analysis" to determine methane, oxygen, nitrogen and other components in mine gas. The column efficiency is high, the separation is good, and the results are satisfactory.
