我国是缺油贫气的国家,煤炭是主要能源,占一次能源消耗的70%,煤层气(俗称瓦斯)是煤炭的伴生资源,却长期成为煤矿生产的最大隐患,随着开采深度的增加,煤层中的瓦斯含量加大,危险性也加大。今年陆续出台的国家新的能源政策,使人们逐步意识到,煤层气是害也是宝,是新的洁净能源。
China is a country lacking in oil and gas. Coal is the main source of energy, accounting for 70% of the primary energy consumption. Coalbed methane (coalbed methane) is an associated resource of coal and has long been the biggest hidden danger of coal mine production. With the increase of mining depth, The gas content in coal seam increases, the danger also increases. This year’s new national energy policy, promulgated one after another this year, has gradually led people to realize that CBM is a harm and a treasure and a new clean energy source.
