煤层气(煤矿瓦斯)作为一种新的清洁能源,在我国有着得天独厚的资源优势,丰富的煤层气资源对于缓解我国油气资源紧张局面,改善能源结构具有十分重要的战略地位。作为产煤大国,我国高瓦斯和瓦斯突出矿井占46%以上,采煤过程中每年向大气排放的甲烷高达150～300亿立方米左右,不仅造成了大量的资源浪费,还给环境保护带来巨大压力,由于不能做到先采气、后采煤,每年瓦斯爆炸事故使国家财产和人民生命蒙受巨大损失。搞好煤层气资源的开发利用,对环境保护和煤矿安全生产意义重大。
As a new clean energy, coalbed methane (CMM) has a unique resource advantage in our country. Rich CBM resources play an important strategic role in alleviating the tense oil and gas resources in our country and improving the energy structure. As a large coal-producing country, China accounts for over 46% of high gas and gas outburst mines. Methane emissions to the atmosphere during the coal mining process are as high as 15 ~ 30 billion cubic meters per year, not only causing a lot of waste of resources but also bringing environmental protection Huge pressure, because they can not do the first gas, coal mining, gas explosion every year so that state property and people’s lives suffered huge losses. Doing a good job in the development and utilization of coalbed methane resources is of great significance to environmental protection and coal mine safety in production.
