煤层气俗称煤矿瓦斯,已成为世界上近一、二十年崛起的新兴能源工业。煤层气已被国内外看作是人类生存发展的第二能源,已成为世界主要产煤国愈来愈重视的一项新能源开采对象。美国、澳大利亚、德国、波兰等主要产煤国在开采煤层气方面,从政策调控,到产业发展,走在世界前列。煤层气作为一种有竞争力的可出售的天然气资源而受到关注。美国煤层气的开采在世界上居领先地位,每天煤层气产量已超过2800万 m~3。由1989年10多亿 m~3猛增到1995年215亿 m~3。我国煤炭储量丰富,产量居世界首位,煤层气资源为35万亿 m~3,相当于450亿吨标准煤,与目前常规天然资源量相当。
Coalbed methane, commonly known as coal gas, has become an emerging energy industry that has risen in the world in the recent one or two decades. CBM has been regarded as the second source of human existence and development both at home and abroad and has become a new energy exploitation target that is paid more and more attention to by the major coal producing countries in the world. The United States, Australia, Germany, Poland and other major coal producing countries in the exploitation of coalbed methane, from policy control, to industrial development, walk in the forefront of the world. CBM has drawn attention as a competitive salable natural gas resource. Coalbed methane production in the United States leads the world with more than 28 million cubic meters of CBM production per day. From over 1 billion m 3 in 1989 to 215 billion m 3 in 1995. China has abundant coal reserves and its output ranks first in the world. Its CBM resources are 35 trillion m 3, equivalent to 45 billion tons of standard coal, equivalent to the current conventional natural resources.
