煤层气俗称瓦斯。它以吸附态赋存于煤层及邻近岩石层中,当其浓度达到5%—16%时,遇到明火便会发生爆炸。中国煤矿安全事故80%与它有关。然而,它又是一种比石油、天然气更清洁、高效、安全的新型能源。我国天然气消费缺口巨大,煤层气作为非常规天然气将是非常重要和现实的战略替代资源。煤层气开发有利于煤矿安全生产,减少煤矿瓦斯事故;可有效减少污染,保护大气环境;增加清洁能源供应,改善我国能源结构。我国煤层气产业历经20余年的发展,已处于商业化开发的初期阶段,具备快速发展潜力,但机遇与挑战并存。
Coalbed methane commonly known as gas. It occurs in the adsorption layer in the coal seam and adjacent rock layers, when its concentration reaches 5% -16%, the case of open flame will explode. 80% of China’s coal mine accidents are related to it. However, it is a new type of energy cleaner, more efficient and safer than petroleum and natural gas. China’s natural gas consumption gap is huge, CBM as an unconventional natural gas will be a very important and realistic strategic alternative resource. Coalbed methane development is conducive to coal mine safety production and reduce coal mine gas accidents; can effectively reduce pollution and protect the atmospheric environment; increase clean energy supply and improve China’s energy structure. After more than 20 years of development, China’s CBM industry has been in the initial stage of commercialization and development, with rapid development potential, but the opportunities and challenges co-exist.
