摘要
The geological characteristics of coalbed methane from the research carried out in Liupanshui is based on analysis of faults, folds, roof and floor lithology, and depth of coal seam gas content, combined with the assessment of CBM resources calculated through buried depth scope, average coal seam thickness, and gas content, organized by the Ministry of Land and Resources in 2006, which launched the “national new round of coalbed methane re-sources evaluation-project to evaluate the coalbed methane resources in the standard category and divided coal-bed methane resources into I, II and III Category of three resources categories. With this method on the other syncline to resources assessment, the area below 1 000 m is named as I Category resources. And with the depth increasing, resources level decreases.
