Coalbed 甲烷(CBM ) 是异乎寻常的气体的一种重要类型。自从 1980 年代，在美洲的 CBM 的商业开发是很成功的。在澳大利亚和加拿大的 CBM 工业在最后十年期间很快发展了。在中国的 CBM 的商业开发在 1990 年代开始了，并且取得了大进步。在中国的 CBM 的地质的理论在开始，出现和累积完成了大前进。在 CBM 开始的方面上，五种 CBM 基因类型(主要源於生物的气体，第二等的源於生物的气体，热降级气体，热分解气体和混合气体) 被学习 CBM 的 geochemical 特征识别，并且一个跟踪指示物系统被建立。在中等高度的等级煤水库的第二等的源於生物的气体的发现拓宽了 CBM 资源的潜力。在 CBM 出现的方面上，在温度和压力的联合行动下面的煤气的吸附规定被在改变温度和压力条件下面进行不同的煤等级的吸附实验揭示。由在 CBM 研究使用吸附潜力理论，而且，在温度和压力的联合行动下面的吸附模型被建立。新模型能精确地预言 CBM 资源，并且克服使用就一个单个因素描述深埋葬的煤的吸附特征的传统的兰米尔模型的限制。在 CBM 累积的方面上，在 CBM 累积期间有三个进化阶段，这被建议，包括气体产生和吸附，不饱和的煤气的吸附，煤气的解吸附作用散开和保藏。由构造进化，水动力学和封上的条件控制了， CBM 趋于地区性在向斜被充实。在在中国的 CBM 的地质的理论的进展不能仅仅改进天然气的理解，而且为 CBM 的进一步的探索提供新想法。

英文摘要：

Coalbed methane （CBM） is an important type of unconventional gas. Commercial development of CBM in America has been very successful since the 1980s. The CBM industry in Australia and Canada has developed rapidly during the last decade. Commercial development of CBM in China started in the 1990s, and has made great progress. The geological theory of CBM in China has achieved great advancement in genesis, occurrence and accumulation. On the aspect of CBM genesis, five CBM genetic types （primary biogenic gas, secondary biogenic gas, thermal degradation gas, pyrolysis gas and mixed gas） are identified by studying the geochemical characteristics of CBM, and a tracing indicator system is established. The discovery of secondary biogenic gas in medium-high rank coal reservoirs has widened the potential of CBM resources. On the aspect of CBM occurrence, the gas adsorption regulation under combined action of temperature and pressure is revealed by conducting adsorption experiments of different coal ranks under varying temperature and pressure conditions. Besides, by applying the adsorption potential theory in CBM research, the adsorption model under combined action of temperature and pressure is established. The new model can predict CBM resources accurately, and overcome the limitation of the traditional Langmuir model which uses just a single factor to describe the adsorption characteristics of deep buried coal. On the aspect of CBM accumulation, it is proposed that there are three evolutionary stages during CBM accumulation, including gas generation and adsorption, unsaturated gas adsorption, gas desorption-diffusion and preservation. Controlled by tectonic evolution, hydrodynamics and sealing conditions, CBM tends to be regionally enriched in synclines. Advances in geological theory of CBM in China can not only improve understanding of natural gas, but also provide new ideas for further exploration of CBM.
